Wax Seal Matrix from the French Site

[PBR]

Went back to our site today and did a little work for the landowners. We were able to hunt for a couple hours and i got skunked. My buddy dug what i think is a Wax Seal Matrix with a crown and some possible letters/initials inside of it. Was wondering if this could possibly be French and if so what the letters might be. . Please take a look. Any suggestions will be appreciated. Thanks UPDATE: I got him to send me a couple more pics of the matrix the way he dug it. It has a silver wire attached with a square shaped silver cufflink or button on the end. The button is plain with no design.

Good research(Although I've seen similar British Crown types as well), now the OP, has to extend his timeline for the site; 1721 is either incorrect or someone visited later.

Tell your hunting buddy Congratz from me! That is awesome! I hope you're able to link it to a household!

I just want to draw your attention to this recent US find. If I understand right, it has a British Hallmark. Plus waiting to hear details on the site.
