The Best Example Of An Aluminum Finger Feeder Error

I agree – one of the best I’ve seen -shows the vast majority of both sides of the coin and the tip of the feet or finger, which I like on these types of examples

Looks like it’s at least triple struck if not quad struck two distinct strikes, and 1 to 2 closely overlapped strikes

Great air, and congrats on the acquisition

I have an issue with calling it a coin, but I like it.

There are many spectacular feeder finger error coins on south american coinage. They are far superior to US feeder finger errors.

Thanks for the info but this is the US Coin Forum

From what I've seen, it seems they could qualify if they were struck by the US Mint

Of course, we need photos!

That is pretty cool!!

It's great that the person who discovered these is on the forums

This is from Mike @Byers:

In 1999 I discovered a small group of U.S. coins struck on aluminum scrap. These were unknown to the numismatic community since this was a new type of major mint error. This group contained a few State Quarters, one Kennedy Half, one SBA Dollar, several Sacagawea Dollars and one pre-state quarter (eagle reverse). After a tour of the U.S. Mint at Philadelphia, it was determined that the minting process had changed to some degree. One of the changes was that "feeder fingers" were used during the striking of all denominations of U.S. coins. Coins from all modern denominations have been discovered that were struck on the tips of these feeder fingers.

Offered here is the only known pre-state quarter with the eagle on the reverse, multi-struck on the end of a feeder finger. It is larger than the diameter of a Half Dollar, twice as thick, shows two ends of the feeder finger, is fully struck and in gem mint state condition. There is one other pre-state quarter with an eagle reverse, struck on a small piece of feeder finger scrap. It is dated 1993, is very small, not dramatic and does not show any part of the feeder finger tip.

There are approximately 40-50 State Quarters struck on feeder fingers. U.S. coins struck on feeder fingers have sold in Heritage auctions for as high as $10,925 for a Sacagawea Dollar and $8,050 for a Madison Dollar. I sold the SBA Dollar feeder finger for $10,000 and two of the State Quarters for $8,000 each. This specific pre-state quarter multi-struck on a feeder finger is exciting since it is the only known full-size pre-state quarter and is many times rarer than a State Quarter struck on a feeder finger.

Here are a few from the original discovery group that I had:

I'm curious the story behind how these were found?

Coinstar reject tray?

Hmmm...MS65 when struck on a feeder finger? How do we know what it is supposed to look like when not struck on a planchet?

Graded like any other coin. This one is clearly MS65.

I don't think that would grade 65 on a regular planchet. I mean, I'm sure it is uncirculated. But there are a lot of marks on the "planchet" and grease. And you've got the 2nd and 3rd strike wiping out elements of the first strike. Just seems like it is hard to grade it "like any other coin".

@Zoins posted a really cool one multiple struck by Roosevelt dime dies a while ago. I think it was better than the ones in this thread.

That was a PCGS MS64 and had nice separation between the strikes. Here it is:

@Byers.... Could you please give further details regarding your 'discovery group'? Always interested in back stories of coin discoveries. Thank you, Cheers, RickO
