Good morning - This coin belongs to a friend, who has asked me to get some opinions on authenticity. I am pretty sure I know whether it's real/fake, but I thought I'd share it here and get some hopefully more experienced opinions. Details: Netherlands 1818 3 Gulden Weight: 28.4 grams (according to NGC should be 39.298 g) Diameter: 38.5mm Silver Content: Tested positive for 90% silver at the LCS Non-Magnetic Photo:
Should be a bit over 32 grams (1 gulden = 10.76 grams at that time) and 40mm diameter, not sure why the catalog information is wrong. Your intuition re: authenticity is correct lol
Yeah, that weight is from Krause (which would explain why NGC's info would be incorrect as well.) I personally don't think it's genuine. I don't believe I stated my opinion either way in the original post - but to me the details just look wayyyyy too weak for it to be real. Of course, that was also thinking it was a good 10g underweight. Now that it's only a few grams under, what do you think?
Guess I just had faith in your instinct Even 3-4 grams is way too much of a difference for the amount of detail left, unless you can see signs of edge filing. But yes, the details are pretty bad. Edit: Wanted to add that's it's probably silver plated copper. Between 12 and 1 o'clock on the portrait side it looks like a piece of the plating flaked off and exposed the core.
I actually tested it on a very expensive piece of equipment at the LCS that they use to test gold and silver bars, so I can pretty much guarantee it’s not plated.
I love world coins in general. It seems dealers (at least here locally) want nothing to do with them whatsoever. I assume it's that they're afraid of authenticity. Bought a large box of foreigns off of a gent some time ago that the coin shop didn't want. $100.00 for the lot and it has yielded many different silver coins and many other aged pieces. Still the best buy I ever made to date.
In accordance with numista.com the weight its 32.298 g https://en.numista.com/catalogue/pieces6552.HTML And here the same info: http://www.coinfactswiki.com/wiki/Netherlands_1818_3_gulden The edge its lettered "GOD ZY MET ONS" ??
Looks like a cast fake to me as well. The edge is also completely off, the raised edge is almost completely absent. It looks like the typical silver plated copper fakes I've seen doing the rounds, I believe from Indonesia. Could be wrong on the origin though..
