I also agree with Jeff... if we're to be of any help identifying these fragments we need better pics.
This is the best I could do with 'Photoscape'... hope this helps, because I have no idea what these are.
The writing on this piece (if that's what it is) almost looks to be Middle Eastern or Arabic in origin.
At first I was thinking it was a gaming piece, but now considering where it was found (on the shore of a beach in BC) it's more likely to be a votive offering.
