Well "dummy" is a little strong in my view :-)
True they are mostly a novelty collector coin with not much precious metal value. I posted this because there was discussion over having a copper round.
The "real" value these coins have are that they can be put into "circulation" and create more interest in bitcoin and evangelize the bitcoin message to the world. Precious metal coins don't get much face time with people other than the owner.
My statement might have been a little strong, but I stand behind it.
I picked up some of the 1 gram silver rounds and shown those to people. The fact that the coin is actually worth more than a "oh cool" factor is a big thing I think. I know I have a couple friends who already want to buy some. I won't be flashing gold rounds to anyone, but the fact I can tell people, "This is pure silver and is worth something!" I would show off these new big silver rounds too. Few more days I'll be getting some..
