First time I've been on this coin forum in years, so thought I'd do a post:
I see many references stating the 'Briot' Shilling where they are really mostly of the standard Tower Briot style (S2799) The 2 shillings here show the differences in the true Briot hammered issue (on left) and a Tower 'Briot' style (on right) - open for discussion to point out the differences..
A little guide for future reference!
