Scott E. Cordry; 2021. Copper Coins of Muscat and Oman dated AH 1311-1316 (1893-1899 CE). ArabianCoins, ArabianCoins.com.
This catalog has been available for decades as copies of a four-page mimeographed sheet with hand-written notes, but is now available
The coins are identified as SC-1 through SC-72 (with a few trailing “A”, “a”, “b”, “c”, “.1”, “.2” thrown in) so the obvious identifier is “SC”, but that might be confusing with several catalogs identifiers starting with SC (SC1, SC2, SCA, …).
If “SC” is too confusing, i would suggest CORDRY.
