I am looking for information regarding the age of this piece, and location of manufacture. It is heavy - about 2lbs and 10" diameter. Engraved with a letter 'G' (I believe) in the center and shows wear with copper showing through. The mark is mostly worn off.. though it appears to include a star, dog and a heart.
I am unable to upload photos, so here is a link on flickr.
Any help much appreciated. MLB
