Is there a coin doctoring technique called "orange-ing" a gold coin?

Longacre

I heard that some gold coins are given an artificial orange-ish tone to make them more appealing. Does anyone know how common this practice is? How is it done and how does one detect oranging on a coin? How subtle is this usually?

I have once owned an "oranged" coin but did not realize it until it was pointed out. Apparently, it can slip buy some otherwise sophisticated pros.

It is fairly common practice, in fact it is one of the questions that I sent to Doug Winter to address in one of his "Blogs" and I hope he covers it. I have a couple of gold 0-mints that are oranged and they are beautiful coins to say the least!!

Reece

In fact if they are dipped after they are oranged, they come out great!! I have a very high end coin that that has been done to, and it is beautiful, nobody yet has to figure what one it is!!

Anybody who can address this one more thoroughly?

first , you soak it in lemon oil, after that , dip it in vinegar to get rid of the smell of lemon. Then the color is obtained by inserting the gold into a carrot and microwaving it for three minutes.

In case this first pass doesn't work, slip the hot coin into a raw potato, skins and all. This will neutralize any chemical changes that may have occured after the first four processes.


Ha.... not really. I'm just kiddin'. Don't try this at home.
