just checked my book Galata Guide to Threepences The coin corresponds to DIG 1ii/Aii, in BCW it is BA-1A (BA-1Ba has a colonstop after ELIZABETH and BA-3Ba has the smaller 14mm inner circle, The rose is 5 there is damage to the top of the rose making it appear as a large rose. There are probable die duplicates in my collection (rn 144) and in the J Hullet (desc) collection no 3. There are listed 10 examples of that obverse and 2 of that reverse
Bust 3F
Reverse is Large Flan BA-a with lions 20 and lis 8
obverse is 332 legend, with one complicating factor for me, that the rose looks oddly like the large rose 4 rather than the smaller rose 5 we would expect for a large flan obverse???
if we agree the rose is 5, your coin is BCW BA-1B:a
But I think it’s a mule BA-3B:a
