    I am somewhat new to buying gold, and wanted to get the forums advice on spotting fake gold coins. I have an AGE, and have been picking up some foregin gold lately as well (francs, ducats, gunieas). I also have some of the recent US commeratives and some candian commeratives as well. My question is if a coin is correct in its weight and size (as measured by a digital scale and caliper), is that sufficient enough to determine that it is in fact genuine? I tried to search for previous posts with no avail so sorry if this issue has already been addressed. Any insight is appreciated!

    also check the thickness, or if you have the materials you can also find the specific gravity of the coin.

    Weight and diameter is good enough unless somebody is out there stamping and plating tungsten. A fake gold coin would have to be obviously too thick or oversized to weigh enough to pass the scale test.

    A common way gold coins are faked is to short the amount of gold in the alloy, say make it 14 instead of 22 karat gold, but still they would not weigh enough.

    If you stick to bullion you are unlikely to get a fake, counterfeiters mostly fake rare dates on actual gold coins to cheat buyers.

    Platinum, iridium and osmium work too ... :biggrin: and uranium and plutonium if I am not mistaken :p (alloy as uranium is slightly lighter)

    when i started years ago .....i was worried about the same thing.....in those days there were not many fakes.......i have confidence today that with a set of calipers,good scale, magnifying glass and acid tester i can pretty well figure it out if i think there is a chance it is fake ....but after holding thousands of coins you get pretty good at spotting a fake......

    The Professur makes a good point.

    If you look around online, on occasion you can find them for resale by individuals(i.e. eBay)

    A buddy of mine picked up a Fisch set for just under 2/3 original price. It was from someone that reached their bullion purchase comfort amount and felt they no longer needed it.

    For some reason it won't work at all with my collection of 100 mil gold-clad buffaloes. But that's ok, I got a great deal when I bought them. :s13:

    Good point, if the gold coin in your pocket is making your balls glow in the dark it might be a fake!~:p

    The gold balance looks interesting .. although the fact that the indent for weighing the coin isn't sized to match each coin might throw some uncertainty into it. But it looks like they only have it for the 1oz coins. That leaves the Guineas, Sovs, Ducats and Francs out in the cold.

    FYI - The gold coin balance has indents for weighing Krugerrands, AGE's, Buffalos, Phils, Kangeroos, and Pandas. I have a gold coin balance in my hand as I speak. It does the exact same thing as a Fisch tester for the coins mentioned above only it costs a heck of a lot less. Strongly recommend.
