Do your research now, before you find another one. Copper, silver, gold? How do you preserve them? Like I said, try subscribing to the PCGS message boards. There is a lot of knowledge there. I would post your find and what you did and perhaps ask them what you did wrong (don't wince).

There are a lot of good people on there with brains you can pick.
Good luck!
