I really hope my US coin source can get me proof one of these.
It looks like they come out January 17, 2018. The price is not listed on the mint site. Let me know if your source falls through. I will see if I can get a hold of one for you.
Get ready tomorrow they go on sale you should be able to buy as many as you want! Happy shopping.
I still like Daniel Carr's version better. He also made an interesting example using his obverse on a silver square for his open house medal.....
I just picked me up tonight one of Daniel Carr's WW1 Concept Commemorative Satin Reeded Edge Round Coin. Round or Square I don't care I will take what I can get. Cant wait for it to show up in my hands in about 1 week or more. At least Daniel Carr's coin will get here Months before the Mint makes the few I ordered.
