What happened to this gold dollar?

Batman23

I was looking at this gold dollar that just sold in auction, I did not win it but was curious to know what happened to it. The holder says repaired. The auction description was "This lightly worn specimen shows evidence of repair on the upper obverse rim, from 10 to 12 o'clock, and the corresponding area on the reverse."

Is the discoloring from heat such as adding/removing something? What are your thoughts as to what the problem was. Is there any cure for this? Would a pocket piece to Good for example clean it up or will that discolor be through the depths of the coin.

It was probably mounted with solder for jewelry use.The solder has been expertly removed, and this is as good has it's ever going to be. The heat that was applied in that area somehow brought copper to the surface, or the dark color has something to do with the jewelry mounting.

I can't even count the number of bracelets I've seen made from gold coins.
The three dollar piece was pretty popular.
Probably to make it "special."

Definitely appears to be former jewelry....the solder removal is done well...not sure why the dark color remains unless they burned the wicking material (used to remove solder) into the surface. Cheers, RickO

If the color bothers you too much, crack it. Much of that discoloration can be restored to a gold color.

I have seen other gold coins (British) in graded slabs with the remark "Removed from Jewelry".

"Jewelry damage"
"ex-jewelry"
"mount removed"

Are all used. I'm not 100% if this was in jewelry.

Thanks for the replies. It seems a consensus on heat being the cause of the color. I would be interested to know why the color happened. Is the color only on the surface or a certain thickness into the surface? I can't see how the copper would move to the surface. How would one remove the color Insider2? Heat, chemical or wire brush?

BillJones

Although The color probably does not go all the way through the coin, and it could removed, the cure for the color could worse than the disease. It would leave a mark in any case.

I PM'ed you. But I see that you don't have the coin so nevermind. NEVER brush a coin (unless you are a Large cent collector).

I am still looking for 1 of those with a hole in it.

A hole would have definitely cleaned up a bit of that color!
