The $7 note is actually very new. Fiji - this year or last. To celebrate the Olympic gold medal in rugby "sevens".
I think you may be right - not many left. Conflict of interest disclosure: I have held three $100,000 bills in my hands. About 20 years ago, the Raleigh Coin Club gave the Smithsonian Money Museum $1000 [our coin show profits had to go to some charity.] In return, we were invited to a behind the scenes visit. I asked to see the $1000 first issue gold certificate; they brought it out, and said, while we were there, thought you might like to see these - the three $100,000 gold notes. They took them out of the holders, handed them to me, and said "Now you can say you have held over a quarter million dollars in your hands."
They printed 42,000 of the $100,000 gold certificates. All of the surviving notes have been accounted for, and are currently in the hands of the United States Government; thus, private ownership of a legitimate example is illegal. Forgeries are relatively common, and have sometimes been known to come with fake certificates of authenticity. A handful of real examples, including an uncut sheet of twelve specimen notes, are currently on display at the Federal Reserve Bank of San Francisco, Bureau of Engraving and Printing, Smithsonian Institution, and Federal Reserve Bank of Richmond.
US I would say the 1792 Half Disme or if you wanted circulation pieces at $4 gold piece. In modern foreign I nominate the Canada One Million Gold which had two pieces but one was stolen from a museum and presumably melted leaving the other one unique.
The $7 denomination is quite old. The Continental Congress issued Continental Currency, beginning in 1775, in several denominations, including 1/6, 1/3, 1/2/ 1, 2, 3, 4, 5, 6, 7, 8, 20, 30, 35, 40, 45, 55, 60, 65, 70, and 80 dollar denominations (based on the Spanish milled dollar, in theory). While some types are quite rare, examples of most denominations can be bought relatively reasonably. Check out https://coins.nd.edu/ColCurrency/CurrencyText/CC-02-17-76.html
I thought about the disme and half disme. But, there are billions of dimes and millions of half dimes. I think it's the same denomination so the ultra rare disme/half disme is not enough. The pronunciation is the same, and the denomination of the half is 5 cents.
SCWC found 132 of them. Quite a few of those are US patterns but regular issue $3 are popular in Canada and Bermuda.
Nice one. Or two. I think we have already found a denomination with two types but that is a nice one which I did not know about.
There are 7 coins in the catalog with a denomination of 1/8 dollar. The others are all in the Caribbean.
It must be something obvious. 1/2 cent. I know of half pennies. A cent and a Penny are different rite?
cent and penny are technically different. the former based on decimal system, whie the latter being based on what became the pound/shilling/pence system. as each is the smallest unit in their respective system, they have become interchangable
