Suspect early electrum type

[glebe]

I have been wondering about this electrum trite for a while.
It combines a very early plain obverse with somewhat later pebbly punches, and seems to be totally uncirculated.
The auction writeup compares it with Linzalone 1070 and Rosen 252, but there is no connection in my opinion.

I am also unconvinced of that attribution. The electrum trite's comparison to LN-1070 appears to be merely speculative, with a vast difference in weights and description. LN-1070 is an Ionian stater and weighs in at 13.34 gm, while the subject coin is presumably Milesian and weighs just 4.65 gm. 

The Rosen reference (online here) is more plausible, described as on the Milesian standard, though the trite is much smaller than the Rosen coin (at 7.014 gm).

Nota: The Linzalone book has an oddly flawed image of the coin.

I'm more worried about whether this coin is genuine, given that I know of no other examples of pebbly punches coupled with an unfigured obverse.

You are right to be concerned. The coin is over 2,500 years old, is otherwise undescribed, and has no pedigree.

[Joe Sermarini]

I do not agree that a lack of pedigree is a reason for authenticity concern. The vast majority of ancient coins do not have pedigree.

[Anaximander]

Here’s an early trite, in the Forvm shop no less. This one does have a pedigree. That would make me a little more confident as a buyer.

Rosen 257.

A 'pedigree' going back 2.5 years for a coin of 2,500 years is hardly a provenance, nor is it in and of itself in any way a warranty of authenticity.

For the avoidance of doubt, I do not have any concern with the authenticity of the Ephesus coin in the Forum shop.

That of the coin posted by glebe is another matter altogether and I can understand the reasons for his reservations, but I have no particular expertise in this early coinage.

from the photo, I assume it's slabbed and one of the big grading services felt it was authentic enough to not reject it for slabbing.  Is it a bulk ancients slab, or a higher slabbing service grade?  Might provide a little reassurance.
