Just landed this nice 1827 bust half. I think the variety is 108 (or 108a) which is an R4 Would love confirmation from an expert! Thanks.
I'd say O-108a Reasons: 1) No visible dot next to star one, reverse: die rust below I in United & wing are missing. 2) Check for die break lump in upper part of the F of OF. Perhaps an interim die state. I hate those.
