Catalonia 1 Peseta 1810, KM 70 [решено]

I believe this coin to be real and the Numista page to be wrong. Billon, 26.5mm / 4.36g.

Edge: Smooth with small holes (man made)

I can see no holes in the edge and as the coin is very thin, I can't see how it's possible to drill/punch holes in it without destroying the coin. I can find no reference to the edge being anything other than plain anywhere except for the Numista entry. My question then is, does this edge type occur across all years and is it possible that the example pictured on the Numista page is PMD?

Weight: 5.25g

My coin is 4.36g in weight. I believe that these coins would be more accurately described as Billon rather than Silver. The term refers to a heavily debased coin with more than 50% base metal content. The amount of silver fluctuated according to availability and price leading to wide ranges of weight. The SCWC dodges the issue by excluding the weight.

Does anyone have an example of this coin for comparison or access to more specialized catalogs which might clear up these two issues?

Yours could be a contemporary counterfeit.
Here listed are some that recently sold at renowned auction houses.
Their weights seem to be between 5.17 and 5.71 the auction sold coins all look to have a higher silver content than billon?

Цитата: "apuking"​Yours could be a contemporary counterfeit.

​Indeed, it looks like silverplated copper

Pretty sure it's billon, it looks very much like those German States coins with a 20% silver content which look silver in higher grades but take on a more copper colored tone as they wear down.

A contemporary forgery is a strong possibility. Knowing the silver content of the original would settle the issue I think. If it's above 40/50% then the weight should vary only a little, if it's a pot metal mix of silver and whatever else was at hand then it's quite possible that the range would go as low as 4.36.

I found two examples while searching, 5.6g and 5.1.

That peseta, the first peseta, was minted by the French army that had been isolated in Barcelona after a Spanish attack. They used the French franc as a model, so it is a coin similar to this one: https://en.numista.com/catalogue/pieces6717.html

They made other coins following the French system in gold, silver and copper, but not billon. The order to make them was issued by the General Duhesne.

Thanks for your thoughts gentlemen. It seems we're all agreed that it's a contemporary forgery.
