I find these coins difficult to grade, so my opinion will probably be wrong, but I shall try anyways.
There is not much details to go by, but at least there is a crown, which appears to have wear. The top end of the C also has wear, and the centre part of the crown looks to have even more, though that could just be a weak strike. The example found here has a similar looking crown and is labelled AU, so it is probably AU-something. Yours does not look high AU, but still higher than the one in the link. Maybe AU-55? Hopefully someone with more experience with this type of coins will jump in and give their opinion.
