London mint, anchor mintmark, minted between 1485-1509. Coincraft reference number is H74D-040, Valued at £38 in VG and £75 in F. Thanks for the pic of the reverse cos it helped me ascribe it to a mint and a mintmark (hence the sceptical bit, cos i wasn't sure about the obverse one), the reverse one is much clearer. (Although they can be muled) Now i don't find Spinks/Seaby catalogue as easy to use at all with hammered... but i figure the Seaby reference is... S.2199 Class IIIc to them. (Or it was in 1993). Tom's the guy you need for this.
