Minted 1 coin

read about the 1849 Liberty Double Eagle at the Smithsonian..made me wonder how often a mint has done this with an issue. Can you name any more?

Well there several patterns that are unique, there are a fair number of die varieties that are unique, just recently Canada deliberately stuck two different unique coins and sold them on eBay as a fun raiser for the Queens favorite charity (They were purchased by a forum member.) So it happens. By the way, they actually struck two 1849 double eagles in gold, not one.

One can say that unique specimens in numismatics are hardly even rare. Consider for
example that some years back there were only some 1,000 known California trade tokens.
These were mostly issued by three or four different companies which provided them for
profit to numerous retailers, saloons, and other such businesses in the state. These tokens
were usually good for some amount in trade and were redeemable at the location named
on the "coin". There was a salesman sample book found in the early 1990's which contained
more than 1,500 different uniface strikes of California trade tokens. In other words one sales-
man for one minter sold more of these token than are known to exist! Tokens were often
collected by a merchant in order to retire them and to forestall their reemergence they would
be destroyed. Those remaining unredeemed were rarely treasured by their owner so tended
to not survive.

This occurs with coins also where there are EITHER small mintages OR low survival rates (espec-
ially when over a long period of time). It can generally be expected that for each unique item
which can be identified there will be another which no longer exists at all.

1870-S $3 gold. Might be 2 but only 1 has ever been seen.

Yes, as has been pointed out, some patterns are unique or have only 2 known. The Indian head double eagle, which is the icon of several members, comes to mind. I own a semi-unique pattern, J.1151. I can trace the existence only these 2 coins, doing research on auctions starting with the Parmelee sale in 1893, and accounting for numismatic literature and shows I've attended during the past 30 years.
