You know I am a sucker for interesting color/toning on these. This one has a unique look, and I like it.
This is USUALLY what happens when the chemical alteration starts to turn...just saying. Oh, and that's just IMO. PS If you like color on Indians, there are a lot of these coins in slabs with attractive blue haze out there - also alterations. Don't try to get them upgraded though, I'll bet the "sniffer" will reject them.
Oh - I'm sure if he did PCGS will come up with a custom holder!!! Cast iron pots, glass beakers, mortar and pestles, etc. I'm sure they can encapsulate them all!!
I kinda think so. Similar reasons, I think - it can only acquire the color if the alloy cake mix wasn't completely stirred.
I've thought it MIGHT be from having putty on it at some point.. but who knows. Some might view this look as a problem.. but I have not seen many like it, so I call it unique, lol.
Gold coins very, very, very rarely have alloy mixture problems similar to what we all call "woodies" on copper (I don't ever recall seeing one yet they must exist). WAIT: ALL THIS IS ONLY MY OPINION. IMO, the OP's coin is STAINED. Whatever was put on its surface either by serendipity or by a coin doctor has discolored it. What we tend to see on gold (IMO) are copper spots, copper streaks (oxidize black) that turn pink when dipped, or struck thru's of various contaminants. The coin is a genuine .900 fine gold coin. Also IMO. You are correct. I've been told by TPGS graders that coins like this have been treated with a certain Antiseptic. Any collector with a raw gold coin that wants something "unique" like this one can just paint it on and drool over it.
I actually thought about this for an hour or two before replying. I bet it passes muster at total weight, but I wouldn't want to read too much into individual XRF readings at given points on the surface.
Wow! Yeah I saw that one on ebay, I think Elizabeth Coins or I'm not sure of the companies name but their sales always end high. Good company to do business with.
