I have a 1oz 2013 gold eagle. It's graded ms70. Looking at it the other day I noticed a copper spot on it maybe pinhead size. Will this affect its value in the future or is it too be expected with gold Eagles? I didn't really pay too high of a premium over spot even with it graded ms70 so I'm not too concerned. Just a curious if buyers look down on a coins with a copper spot (only one so far)
I'm not sure with copper, it's pretty open to oxidation. I wonder if you run a low current through your copper stack it will prevent it, like a .5 volt phone charger hooked up to it should work, theoretically. Good for keeping car batteries trickle charging too.
If it has a copper spot that's not a bad sign as AGE's are about 5% copper so more than likely it's not a fake. It would affect the value slightly as grading are for perfect coins. All depends how much you're selling for. Ditch it now and buy a spot free one if you're already worrying about it.
No, it is certified from PCGS but I guess that can be faked too. I don't see anything on the coins that would make me think it is fake though. Are fake gold Eagles common? I haven't read too much about fake gold Eagles but the few that I have seen were pretty terrible fakes.
Not really too worried about it. It's a gold eagle so I can't imagine it will ever be worth much more than spot anyway. I was just surprised it has the spots coming so fast. I looked at it closer yesterday and there are a few for more on the back of the coin as well. Was really most curious about what happens when a coin that is graded has this happen after grading. Is it still considered a 70 or is the grading pretty much out the window at this point?
Real gold coin cheaply sourced Chinese produced slabs made with inconsistent materials that have a chemical affect on metals over time.
Here are a couple pics. The only noticeable spot on the pics is the one just above the elbow. For some reason they do not show up as well on pics as they do in person. I couldn't get any better pics with my phone. Source:
