You should put them on airtight capsule to protect them from scratch and discoloration. Most your have noticeable scratches. I'm just concern about this gem safety. You can buy copper membership in the forum so that you can post picture in your thread. It will makes easier for visitors to view your coins.
GLWS!
Perhaps I should have. I am not a collector however. I bought these as conversation pieces to show people when I was introducing people to what Bitcoin was back in 2011-2012. They were worth about $5 and I didn't care. I'm still not a collector and would rather have coins on my ledger, but I don't want to destroy something rare that others may value so I'm attempting to sell them for a markup worth my effort and risk rather than peel and destroy them.
The one exception being the 10BTC piece I actually bought that just because I thought it looked really cool and it is in a case that has never been opened.
