It's not a coin, but rather an early "AVE MARIA" French-style jeton, or counting-board token. This Chicago Coin Club website is old but still has lots of good info on the history and use of jetons; figure 18 is not too dissimilar to yours, but has a modern-looking crown on it rather than the Crown of Charlemagne featured on yours. Yours probably likewise dates from around the 1300s-1400s, judging from the style of the lettering.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
