Chinese cash coin S-634 or 633 [Risolto]

Bronze, 3.7 gms, 24 mm

I just purchased this coin as S-634.  On-line, I can find references to this coin.

Numista lists S-633 and shows this coin as almost an approximation.

Any insight?

Thank you.

Please, give us the link to the Numista sheet !

Found it:

N#61311

Comparing with my own coins, yours is Hartill#16.430

I don't know wich refence is equivalent in Schjoth catalog, sorry…

My notes have Hartill 16.428 connected to S# 634 and Hartill 16.429 and 16.430 connected to S# 633.

(And all of those matching FD# 1076.)

Unfortunately I don't have access to my coins or books today.

Thank you so much for the help.
