start your own unique thread. Pictures a must! This thread is very old (2009) and some of those members are no longer on CoinTalk
Some of the steelies were dipped in a copper wash to create a fake copper 1943. Or what Paddy said in post 21. Just woke up, so I missed it.
Best to start a new topic instead of posting on a 9 year old one. Chances are you're seeing things, but pics will help.
