I bough this coin https://en.numista.com/catalogue/pieces20870.html
Weigh is ok, diameter is ok, thickness is 0,75-0,8mm ( I donīt know what is original)
Looks good and also edge looks genuine. ,,Ring test,, is also ok I guess. Non magnetic.
Till here I didnīt have any problem, but when I tried diamagnetic test, the neodym.magnet just slide down without any resistance. Its 2mm diameter small neodym.magnet.
If I tried the same test with 1964 US silver ,,one dime,, there is nicely visible the resistance and slow motion of sliding.
Also my 5 gram gold bar in plastic cover doing the same.
What do you think? Possibility of counterfeit?
Coin is not rare - almost price of pure gold in the coin and is bought in numismatic store.
Can be no-reaction based on thicknes or on purity of gold? - 0.900
Is it normal with other types of small gold coins?
Is here some other test fot it?
Thank you and have a nice day!
