The usual way these modern
fakes are found is that the tour guide or construction worker drops it on the ground / in the trench, and then lets someone else discover it. These stories have been told on
Forvm many times. I recall where someone claimed to have dug up a modern
fake 2 metres down in the desert. No-one could
work out why any coin, ancient or modern, would be 2 metres down in the middle of a desert,
nor why anyone would choose to dig at a random spot in a big desert to find it. 2 metres is pretty deep! Other usual places to find modern
fake coins include in attics, grandfather's old box, or left in a will. Often people who ask our views on
Forum come with totally innocent intent, having been told these stories by the persons who sold them the coins. It does not matter where the coin was reported to have been found. If it looks a certain modern
fake, then ithat's what it is, and perhaps then the story of where it was found was
fake too, or the finder was deceived by a tour guide or construction worker who planted it.
PS: I
still have fond memories of that button where the other
side was too secret and mysterious to show.
PPS given that it is 10mm in
diameter, might it be a indian gold fanum or modern
replica thereof? In any event, if it's something like that it's maybe worth its gold value which can be checked by weighing it.
