Hi there, I'm getting interested in buying (some) Casascius coins. BUT... there is something that worries me, I have been thinking to post this or not, but I just go for it.

Because the coins are not being made anymore, and there are only so many around. You would say the price will go up because they are original and getting more rare. But what if somebody sends a small amount of mbtc to the public adress of one of the coins, then it's not original anymore! You could say, Ok but now it has even more BTC value, but it's also not the same anymore as Mike Caldwell made them and sold them in that way, would that not be negative for the value.

Let's say I have a coin made by Casascius in perfect condition, and I have a second coin just made after the first one but it has a scratch on it. Then you would say the second coin is less valuable because of the scratch. But now I have a coin with exactly 1BTC, and the second is 1.0000001BTC (or something). Would you say the one with 1 BTC is more valuable or the other with the extra mBTC?

I would like it to stay in the way, like Mike Caldwell made them but thats just my opinion. What's your thought about this?
Thanks
