Japanese Canadian - Beaver - postage stamp ingots

Beavers seem to be a thing around here
I hadn't seen these posted previously, so here they are.

In the 1970s an outfit called "99 Company" of San Clemente California produced various numismatic and philatelic items. They were a competitor to the Franklin Mint. Both entities produced a neat set of postage stamp ingots. The 99 Company issues were nicer, in my opinion. They were larger, thicker, heavier, had color, and had a hefty pure silver base (Franklin Mint issues were .925 fine sterling). One of the 99 Company issues was a representation of the first Canadian postage stamp which featured a Beaver. There were two types of ingots: "Jeweler's Bronze" and Silver. Both were die-struck like a coin and then had a cloisonné style translucent glass enamel overlaid on the relief. For the Beaver issue, I think the bronze one actually looks better (clearer image of the Beaver) because the color of the bronze metal allowed less (and clearer) enamel to be used to achieve the desired final color. The silver issues typically contain 15 to 20 grams (net) of pure silver. They are marked on the back "1000 FINE SILVER JAPAN". The "1000" designation seems odd compared to the usual "999", but Japanese and European items often used the "1000" or "1.000" markings for pure silver. Originally they were all mounted to a card with information about the particular postage stamp. The 99 Company produced other postage stamp ingots but I don't know how many different types there are. The last picture (below) shows some other ones that I am aware of.

Typical reverse-side marking:
