Ahhhh, now that's interesting, to be honest I Identified the coin to be a Charles I, Half Groat, 1638-39........the Briot's Mint came about as it doesn't mention the Tower mint and I took the Anchor to be Briot's..... just adding to the novice confusion the Anchor maybe Upright, Inverted, Horizontal to left or right.....it does however (and quite correctly) it mentions that S2856A as a milled coin by Briot's Mint 2 pages further on.....which i didn't see as I was looking at Hammered only coins. many thanks Rob for the correction 🫡👍Cheers "H"
