Tarim 1 Dinar AH 1352 Fantasy Coins

There are two sizes of 1 dinar AH 1352 fantasy coins now listed under Yemen/Tarim (at one time, I believe they were cataloged as "Arabia"); each size was struck in various metals. One example is listed in the Numista catalog here:

The Numista catalog--as well as the NGC World Price Guide and the Unusual World Coins Catalog (6th edition) all list the size of the small versions as 23mm. Since all three of these sources are usually sourced from Krause Publications, they could all be wrong.

The three small coins--three different alloys--which I acquired some years ago are 21mm in diameter.

Although none of the Numista members has reported having these types, can someone verify what the diameter should be? Three were listed in MA Shops, with weights but not diameter, which could mean that his did not match the 23mm size.

The one large size I have does match the 38mm size, but I have not verified its alloy.
