I would take up all the server space on this forum if I were to post all my Unique coins.
Hey now this is a Modern Crapless thread

If world coins are okay and not cheating...
Aside from a chop marked Trade Dollar (never saw two chop-marked coins alike)... I do not think I have any 'one of a kind' coins... Have to think about that...Cheers, RickO

Not a coin, but coin silver.

As far as I know, this is unique:
John M Smith, Nashville, TN c.1820-30 coin silver beaker:

These were over struck at Dan's 2013 open house on an Ike dollar provided by an attendee so are unique, one of a kind, examples.


That would be very cool to provide a big silver dollar and have it overstruck. Glad I saw this. Peace Roy

Not positive about this one being unique, but with a total graded population of rpm-5 of 4 coins, I'm pretty sure that this is the only one in the terminal die state

"Coin collecting for outcasts..."
Wow, Grip. I had no idea....

Here's a warning parable for coin collectors...
Token made by my father.
Paper money eventually returns to its intrinsic value. Zero. Voltaire. Ebay coinbowlllc
well, Too bad it is not a US note..

there is ONLY one other known. It is in "jail" at the Canadian currency museum in Ottawa.....and is a lower grade.
I am thinking of selling it.
wondering where the others are?
There must be a story behind that great token. Come on..spill the beans.
My father is an engineer, and he made it in the 70's by chemical etching. I believe he probably was going to use them as a poker chip. He made a few 25 cent pieces too. He gave them to me some years ago, and i generally carry 1 for luck.

This sure looks like something struck on a silver planchet.

The more qualities observed in a coin, the more desirable that coin becomes!
