quercus

Recent events have shown the importance of provenance. There is special emphasis on coins with provenance before 1970, when the UNESCO treaty on the Ownership of Cultural Property was adopted. Please use this thread to discuss any coins you may have with robust provenance. 

I spent a few moments doing some acsearch sleuthing as @Kaleun96recommended. I did find a Le Rider plate die match for both the obverse and reverse (thank you for the helpful reference). I've attached a quick obverse die match study I put together on Photoshop, alongside the coin with matching die (2003 Busso Peus). I didn't bother doing a reverse die match study on Photoshop because the die match is obvious.

Although as he mentioned, the question of whether this may be a transfer die also remains.

I do not see a coin picture in the first post. Was it removed?

Oops, I just realized I accidentally removed it while editing the original post.

I am certainly not an expert in this area, but nothing about the coin screams fake to me. That's a very nice portrait of Zeus on the obverse!

Edit to add: Welcome to the Forum! 🙂 

Thank you for the welcome! I've mainly been focusing on Roman coins these past 2-3 years, so this is a new arena for me. 

I recently won the pictured coin at the most recent Spink auction, and after taking a further look, I'm a bit concerned about three details:

1. The coin is slightly underweight at 14.04g (vs. the standard of ~14.40g)
2. There is noticeable pitting all over the obverse
3. What looks like a seam from 10 to 11 o'clock on the obverse

With that in mind, what do the fine people of Numisforums think of this coin?
