Hi, Wow, has it been a long time since I've posted to this NG. My wife and I are currently cutting a few topaz stones for a client and these topaz are unlike anything we've ever seen. They are taking a polish in a most difficult manner and this is forcing us to consider some alternative...

I'm in the UK BTW, so it's not a local stone, nor common, and I certainly don't know anything about it myself. My plan was to...

They are all 5 cent pieces bearing the legend MoM 902.7 (or OoS 902.7) 5 centavos on one side and REPUBLICA MEXICANA with the date and an eagle holding a snake on the other. These appear to be silver, anybody know...
