Hot peroxide treatment of coppers....

[TrpnBils]

Let's see some success stories.... Everybody seems to rave about this on here but I have made a promise to myself not to try this on any coppers this year because they seem to come out looking worse than when they went in. Always dry and crusty....Does anybody else have this happen? Are there certain coin conditions it works better on than others?

Not sure what this Indian head is made of but it turned out great, I assume not all copper as other pennies did not turn out the same.
This coin was so crusted I did not know it was an IH
I used an electric potpourri pot and took it out to scratch it with tooth picks about every 3 or 4 minutes.. for hours on end to get to this.
I think if you go too long it starts to damage the surface. After I finished I washed it with dish soap, then soaked it in water over night. After it was dry I coated it with Vaseline.

I've had the best luck on wheaties and IHP. LCs just don't seem to clean up well. Maybe the coin composition, maybe the age, maybe a mixture of both.
