This is probably way off topic but I've had this for quite a while and have never really given it much thought. It appears to be a blank planchet, 10mm and 1.3gms, with typical patina and perfectly flat surfaces on both sides. I would think these have been found before but probably have little numismatic value which is why I've never seen another one. For myself, a collector of the little late Roman types, it is really kind of interesting. Any thoughts?
I'm looking at it as hard as I can to distinguish something but its like looking at clouds. Actually, clouds would be easier. Just looks too far gone for a proper ID, at least for me.
You won't find any design on it, it's a blank that's never been struck. What's interesting is that you find these with modern coins but I've never seen one for ancients. It makes perfect sense, but I never really gave any thought in they had to prepare each planchet with very flat surfaces for a good strike. I just assumed that they struck coins haphazardly 1600 years ago. I suspect I was wrong.
You could compare the weight to struck coins to see if it was blank vs worn down but I doubt there's much interest in an ancient blank as opposed to modern prepared planchette that is unstruck.
My fault, I had misread your original post and thought you had wanted an ID. I've seen so-called blank planchets sold on occasion but I don't know enough about them to know if they really are blank or are just that worn down, but I think H8 Modern's advice on comparing the weights is a good one.
I took a quick look at the weights and sizes of Leo ae4 coins and they are right around 10mm and 1.3gms so that's probably the time period that this blank planchet was made. I don't really think it's worth much but as I said it's interesting to see that the surfaces are very flat and parallel to each other, similar to how the planchets of today look.
