Syrian Coin Question

In 1950, the Syrian pound (or livre) was a smallish gold coin, weighing about 3/4 of a sovereign. A 10 and 20 pound gold coin would be quite large; larger than just about anyone else was issuing in 1950.

It doesn't appear to be a Krause glitch there aren't any "missing numbers". And there aren't any Syrian coins listed in the "Unusual" Krause book.

So I'm not sure what's being referred to, here.

I recently bought a 1950 Syrian half pound ex. John J. Pittman collection.




It may be a long shot but since this coin is dated before that sale and from Syria I thought he may have bought it in the Farouk sale.
It's not a particularly rare or expensive coin (mintage 100,000) but like many of Pittmans coins it is of high grade.

The 1954 Farouk sale catalogue lists only one Syrian gold lot-#1285 containing 2 1950 20 lire and 2 1950 10 lire gold pieces in MS "very rare." Apparently hammered at 34 pounds!
