I would not want a copy of any coin. It would take the fun out of collecting the coin to me. Come on you guys and gals know what it feels like to have the real coin in hand and it belongs to you? There has to be something lost there in having just a copy of a coin.
I think the coin would be nice in varying denominations. It would be neat to know that in a handful of coins I would have a large sum of money vs. carrying a wad of bills. That way if I'm robbed I can throw a handful of coins at the crook vs. handing him my wad of bills.
