Silver plated Roman Denarius [решено]

Hi I believe this is a silver plated Vespasian Denarius. I think the solid silver coin is quite rare. Could anyone please tell me what the solid coin would be worth and what this plated coin valuation is? The diameter is 17mm and weight is 2.78 grams. Thanks.

Coin struck with a base metal core that has been plated with a precious metal to look real are usually called fourrée. They're basically counterfeit coins made by forgers and not the ruling authority although I have heard of the Roman authorities making such coins also when they ran out of money although I have no evidence of that.

Your coin is a fourrée RIC 2 (RIC [1962] 15), RSC 226, BMC 35, denarius. Here's a real example that sold at auction in 2008 for 600$ while it's expected value was 375$: http://www.wildwinds.com/coins/sear5/s2296.html#RIC_0002

It's hard to put a realistic value on yours, you first have to find someone that wants a fourrée in his collection and then work out a price. Personally, if it was my coin, I'd try and sell it for 15$ but would accept 10$ if offered. This is just my personal opinion based on my experience with ancient coins, it could be way too low or too high. I did find a site selling a fourrée for 289$ but I don't know if it sold or not, also I don't see why anyone would pay 289$ for a fake if a real one is around 375$: http://www.jerusalem-coins.com/IVDVEA-Denarius-of-Vespasian-70CE-p/jc1479h002.htm

Also, to me, this looks like a more modern fourrée, not an ancient one. I can't really explain why but the surface and lettering just look more modern to me. It's a valuable coin so it's desirable for forgers to reproduce.

EDIT: after a little research I found that for some reason most examples of this coin are fourrées and prices on them are all over the place. If yours is real (as in a real fourrée, not a modern one) it's price is higher than my original estimate.

Hi thanks for the reply which was really interesting. I've only every seen washed counterfeits or coins that have had tinning applied. So your info has been really informative. I can confirm the coin is not modern due to the location it was found. Thanks once again.
