The unsuccessful 1/2 of an attempt to make a fake error? Squeezed in a vise with another coin?
Part of the reverse has been flattened; the rim, C of Cda. date, and leaves have been squished. Most of 1 CENT and CANADA are intact. On the other side, the REX is crushed, but GEORGIUS isn't. Is the lettering cut or is it a raised rim ?
Can't quite figure it all out. Please post a couple more photos, that obverse is like a Rorschach test; I see a trident.
