Hi folks,
I'm new to the forums and glad to be here.
I've been hunting for a Louis XVIII 5 Francs silver piece (KM# 702.1) for several months, and finally found one for a reasonable price.
This is my question: is it authentic? I know this example has excessive surface scratches and was improperly cleaned, likely with chemicals. This resulted in a poor surface, but it's still a nice example of a difficult year to come by.
The diameter and weight are correct. The edge lettering is correct. The ONLY issue I've found is that its ping test sounds a little "off." When I use a cull
Peace dollar to lightly tap the rim of the 5 Francs coin, the sound is a little dull. It's not as clear and high-pitched as other silver coinage. Is that enough of an issue to call the authenticity into question?
It was purchased off
ebay (I know, I know) from a dealer with great feedback and no issues that I know of. Moreover, I've never seen a fake coin of this year/mint, but this doesn't mean they don't exist.
Thanks folks! I really appreciate the help.
