Jagged Edges On Coin Features?

Perhaps the explanation is not sinister and is simply attributable to some technique the Ilkhan (and other?) die engravers used? Are these details seen on other Ilkhan coins? I never looked for them and so I don't know.

Having said that, I have read numerous times that parallel ridges are evidence of modern dies that were engraved with power tools. There's an article at Forum by Ilya Prokopov about this, and in it he mentions that "eliminating tracks on slopes" - meaning the sides of engraved letters and other motifs - is harder for forgers to do (conceal) than the high points.

Not sure that's what is going on here, however. Hopefully the coins are kosher. But, for comparison, here are pics of modern fakes struck from dies engraved with power tools.

I am very much inclined to agree with the opinion of Bob L.
That is, evidence of a particular die engraving technique.

If it was a sign of metal flow it would be radial from the center. In the case pictured, those tiny lines are random in their direction, and so provides my confidence in his opinion.

Not expecting much of a response due to the nature of the subject, I sent an e-mail to Steve Album (or rather, his staff).

Their response was:
"These are simply engraving marks left on the die by the diecutter tools.
You were commonly see them on the larger silver coins of the post Mongol era and of the Mughal empire of India."

I also asked two collectors of such coins, both replied, and one of them provided an answer which matched the one above, while the other did not contradict it either.



Perhaps, under magnification, these lines look different, than those on the modern fakes - we don't have high quality images after all.
