Entirely a personal choice, but I tend not to bother grading 1 oz silver coins as the cost is a bit disproportionate to the value of the coin

Thats just how they come from the mint I'm afraid!
You can get an air duster and carefully unscrew the capsule and use it to blow the stuff off - the compressed air in a can type stuff you use to clean electronics.
If you decide to go down the grading route, tick the 'conservation' option and for about £12 they will do it for you before sticking it in a slab.

These two arrived today 😍😍
Absolutely blown away by the Beasts 🙌🙌
