Coin guides

Grading and mint identification for English hammered and British milled coins, written from the reference tables this catalogue runs on — 187 initial marks, 944 legends and 273 mint signatures across 105 mints. Free to read, no account needed.

Grading

What a grade actually means, what wear looks like on each series, and how the four grading systems a British collector runs into line up with each other.

Mint identification

Where a coin was struck, worked out from what is on it. The initial mark and the Latin legend are the two kinds of evidence, and they behave very differently on hammered and milled coins.

Tools

Pick a mark, type a legend, get a mint and the reasoning behind it. Runs entirely in your browser.

Where these come from

YourCoins is a private catalogue for a group of coin collectors. To work out where a hammered coin was struck, it carries a compiled reference of every initial mark, legend and mint signature in the English series — and those tables are just as useful to somebody who is not a member, so they are published here. The grading tables are the same ones the catalogue grades with, generated from the same code, which is why they cannot drift out of step with it.
