I don’t know what this is or if it is even authentic.

what is this and is it authentic? I put a quarter next to it so you can see how large it is.

It is an Ecu from France, Lille mint. It appears to be real. If you are able to weigh it, that would help in determining if it is authentic. The first test to try is see if a magnet sticks to it, if it does, than it is not real- as the real coin is a silver coin, and would be non-magnetic. (There are many fakes made out of brass or other non-ferrous metals, so it not sticking would still not rule out a counterfeit or copy). If the magnet doesn’t stick, then use a digital scale to get the weight. If the coin weighs right, it should be good. Also if you have access to a caliper, measure the diameter of the coin. Please post back the results, so we can determine if the coin is real.

 

It appears to be overstruck on an earlier ecu from 1696. Many of them were. Here is a general image of the undertype. The image is from a dealer on MA-Shops.
I don't know this series well enough to verify authenticity though. Good luck!

 

I will get the information requested and let yall know as soon as I can. I dont think I have access to a caliper, but I may. Thank you so much!

 

Welcome

 

Nice coin
I really hope it’s authentic. Looks alright to me but there are some good fakes out there.

 

@Cindy Medford, if you don't have access to a caliper almost all 12" rulers have a millimeter scale on one edge. That will give you a ballpark figure.

Cindy - you might find this of interest - 3 different, very inexpensive calipers in metal. They also come in plastic and those usually only cost a couple dollars.

I want one of those. Nice real coin

 

Hi there,
any results of your research? Very curious about it
As @Milesofwho mentioned before, it seems as an overstruck - a similar item you can see here:

Maybe Stefan Knopik can give you more details about your coin - just view the link and go to "Question about this item" and ask him, maybe he can help you (not 100% sure, but it could be a possibility)

Otherwise @Bayern seems to be good into this, just let us know your results, if you could find omething interesting about your found... Have a wonderful weekend,
Cheers Sarah
