Please Help With Our Unidentified Coins

First coin is a Parthian drachm of Vonones II

I think it is genuine.

Second I think is a penny of William I; I doubt that it is authentic. Looks an awful lot like one of these:

I'll hold off on the call on the sovereign; any coin dealer should be able to assess metal fineness at a minimum. I don't collect sovereigns, but my understanding is that practically any wear reduces them to melt value only.

Yes to the first coin being a Sellwood 67.1 Parthian drachm. But the attribution to Vonones II has recently been challenged as a result of the research of G. R. F. Assar. The new attribution for this issue is Meherdates, a usurper, 49-50 AD.

Sellwood 67.1 (Vonones II)
Shore 368 (Vonones II)
Sunrise 417 (Meherdates)

Hi everyone

Thank you all so much for helping us identify the coins.

According to my kitchen scales the second coin weighs around 4 grams and it isn't attracted to a magnet.

I have tried to upload more pictures of it, hopefully they might be a bit better. I have had to use the image optimized to make them smaller files so may have affected the quality.






Thanks in advance.

Re: the William coin. Sorry, but I have bad news.

Do you see the little letters "WRL", stamped into the field just to the left of the king's neck? Those are the initials of Westair Reproductions Limited - a manufacturer of replica ancient and mediaeval coins for the British tourist trade. You can find WRL replicas for sale in just about any museum or historic site's gift shop. They are usually sold for a couple of pounds each and come in a little information card like this one on Amazon, telling you that the coin is a replica and with information about the genuine coins, but of course, all of that is lost once it is taken out of the wrapper.
