Question 1: What was the largest gold coin that circulated as legal tender?
The 4000 reis or moidore, a Portuguese gold coin, with a value in federal money of $6.
Question 2: What was the smallest gold coin that circulated as legal tender?
The Spanish 1/2 Escudo, often called a "gold dollar" or "half-pistole".
Question 3: What was the largest silver coin that circulated as legal tender?
The Spanish eight reales coin, commonly known as the "Spanish dollar" or "piece of eight".
I got these answers from Google AI, but I think they are correct.

Largest gold coin.
British 5 guinea
The 20,000 reis of Brazil May have been the largest gold. Almost 2 Oz. Just picked one up.
We have a correct answer to question 1, the Brazilian 20,000 Reis

ChatGPT gave me the same answers as @MidLifeCrisis. When I asked about the correct coins it validated the trio. Can't trust the machines...yet.

I'll guess the largest silver coin was probably a German Taler or multiple.
The Maria Teresa Taler was a first class coin, and while large, is still smaller by diameter and weight than the largest.
Also note, talers weren’t specifically authorized like other issues were. Of course they still traded but by bullion weightvs a set exchange like other countries. Maria Teresa talers were the exception given their premier status.

Many foreign coins circulated here, but only certain ones were legal tender as specified by various coinage acts, beginning with the 1793 act and ending with the 1857 act. A fun and educational collecting area with almost endless possibilities. No German coins were officially legal tender, but many were accepted in commerce.

Perhaps of interest, the seller of the 1725 20,000 reis I just bought was threatening, perhaps facetiously, to
melt it when gold was about $5,500/oz. I paid about $5,600/oz. for a beautiful AU details with a tiny test cut. Would have been a damn shame if……
I am not sure if any British Crowns made it to North America…. Could be the French Ecu

Portugal 400 Reis for smallest?
The French Ecu!! Other variations of the French crown sized coin also count (6 Liveries as an example)
41mm vs the 38-40mm Spanish 8 reales.
29.5g in weight beats the 27g Spanish 8 reales

Great guess, but no!

As you might guess many English coins circulated here, including crowns. The earliest English coin I have is a half groat of Henry VII. One was found in Newfoundland, close enough.
I picked this up at FUN last month.
Pretty typical example, I guess. Has adjustment marks, as so many do, but since they were softened by the striking of the portrait, I do not find them objectionable. Kinda liked the grey tone.
Collector since 1976. On the CU forums here since 2001.
Indian Fanam for the smallest gold?
Nope. Might have circulated but was not authorized as legal tender

Spanish 1/2 Escudo…..?
Nope

The Republic of Mexico minted a 1/4 escudo coin in gold, but I believe it was larger than the other guesses. My sources don’t show a gold Portuguese or Brazilian gold coin smaller than 400 reis.
I, for one, am prepared to learn something.
PS I’m disappointed that the moderator moved this thread. Anyone collecting US coins should be interested in all coins that were legal tender, not to mention that our coins were derived from the foreign coins that circulated here. The 8 reales is even in the Redbook for Pete’s sake. God forbid US collectors should learn the history behind their coins.
I would also note that a number of foreign coins are included as “Colonials”, which I believe are classed with US coins.
I’ll give this to you...
The Portuguese 400R is 1.072g while the Brazilian 400R is 0.8938g. So the answer is the Brazilian 400R.

Seriously! @PCGS_Moderator, can you please move the thread back? The intent is for this to be education for US collectors on the coins of Early America. Lord knows there are enough threads on Vault Box and all the other nonsense to dull the wits.

I was focused on the dimension. I think both are about 15mm (?). I hope the moderator listens to us. I was annoyed with the movement of the PM thread recently as well. PM prices can have a profound effect on US coin prices and availability, not to mention general “market” activity and show attendance. I could see moving routine PM posts, but the current state is hardly routine.
The real issue is what was accepted as legal tender- And just to illustrate that point, 8 Reales were accepted as legal tender up to around 1856.
In view of the French presence in North America, it really should not be much of a surprise that the Ecu was utilized.
As for the GB Crown, one has to consider that Crowns from the reign of George I and George II were not produced in large quantities. Even in the 1740-1760 time frame. the George II Crowns were not often encountered. And then you have the period after 1751 whereby a crown sized coin was not minted in GB until the BOE Dollar in 1804. There was the counter marked coinage on various crown size coins in the 1797-99-time frame. The mostlikely crowns that perhaps made their way to the colonies would have been from the recoinage of 1696 featuring William III. Coins from England were used in the colonies, but I suspect most of the coinage consisted of lower denominations.
Coinage really needs to be recognized for the purpose it served which extends beyond geographic boundaries. We should embrace history and how commerce developed in the Americas. And such a discussion is not out of place on the US Coin forum.

Were Brazilian 400R actually circulating in the colonies? Same with the Portugese smaller gold fractionals.
Well the 4000R and 6400R were one of the most common gold coins, so I’d guess the smaller denominations were also prevalent.

Unless a coin is recovered here or from a shipwreck, mentioned in a newspaper, assayed by the mint or turned into the mint, or otherwise documented, we’re probably stuck with extrapolating from those examples that are documented. A very odd assortment of coins have been recovered in Jamestown * for example, which suggests that almost anything might have been used by colonists or merchants arriving in the US. Money was scarce and they used what they could get their hands on. Even after 1857, foreign coins were accepted for some time, particularly in rural areas, although they were no longer legal tender. I’ve relied on the research of others, inventories from archeological sights, famous hoards, the odd reported dug coin, old newspapers, mint assays, etc., filling in the blanks between denominations and time periods pretty liberally. As one might imagine, gold was not plentiful, but the examples we know about give us a great excuse to collect a wide variety of similar issues.
No response or movement from the Mods on getting this back to the US Forum.

As I heard this type was used too in the Colonies. And it named "dogt". And as I read British government forbade passing British coins to the Colonies... But how did they pay to soldiers and servants?

This is a link to an earlier discussion about a regulated (Brasher) gold 1600 reis. https://forums.collectors.com/discussion/1015790/brasher-2-gold

Does anyone know what the smallest regulated gold coin was? A ¼ guinea is known (Garrett), a bit more than a dollar.
A regulated 400 reis would be very cool - a gold half dollar?

2: How about California fractional Au? Mintage began in 1853 (pre-1857)) and in denominations as small as 1/4 dollar?
Maybe if they remove the Humor, music, random picture threads then they'll have room.

This forum has gone way downhill in the last decade. Stupid crap like this from the mod just makes me want to leave like so many others have.

I find it incredible that this thread was moved to the World Forum, while other requests for service go unanswered.
My current "Box of 20"
I'm also stunned that this was moved. I mean, who would think anyone would want to know what was authorized to be used in this country?

An interesting historical example of this can be found in a table in the book The Gold Coins of Newfoundland 1865-1888 where an 1894 payment for insurance consisted of gold coins from Spain, Germany, the US and Newfoundland and the silver coins were from Spain, Greece, France, England and Germany. Granted, Newfoundland is not the US, and it wasn't part of Canada at the time, either, but money could be scarce and people used what they had on-hand.

The various pcgs_xxxx tags come and go. Best to flag a post. I'm going to flag mine and maybe we'll get somewhere.

I suppose the trivia has been asked and answered so I should just let it go. The whole issue just aggregates my broader issue if the downward trajectory of the forum itself.

The moderator closed an interesting thread discussing the use of lead bullets as money in the early US colonies. Colonial money as it were. Poor judgement, limited numismatic background.
Were the Dutch ducatons ("Silver Riders") at 32.5 g not accepted as legal tender?

I don’t believe any of the coins of the Netherlands were legal tender, but were nonetheless used in commerce during colonial times according to
my sources. I’ve included numerous coins from the Netherlands in my “US” collection. Copper, silver and gold. I included a Silver Rider and a Gold Rider.
Act of February 9, 1793
An act regulating foreign coins, making them legal tender, and establishing their value, etc.

There were several updating Acts subsequent to 1793 as well, Certain coins of some former Spanish colonies and Brazil were included as legal tender after they achieved independence; and the French 5 franc coins were added, for example. Again, many foreign coins were accepted in commerce that were not included in the Acts as legal tender up to 1857 and beyond. Endless research fun.
