It is a Louis XIV French Liard, the coins did circulate in the colonies, my son has found a couple and I am hoping I found one this past week. Is this a ground find? If so, congrats, since the coin shows quite a bit of detail compared to the ones my son has.
If you get a chance could you measure it, should be around 22mm in diameter, weight also if you can.

Thanks Don, it weighs 3.0 grams, without a ruler handy, it is just larger than a u.s. nickel, but only half the thickness. it was found in Mass. by a friend of mine. thanks to all!!

if anyone's interested, this may be on Ebay soon.
