I have a run of them, 84 to 91 I think. They were silver, bronze and aluminum, although the aluminum ( the planet Munimula spelled backwards

) did not come out until 85 or 86 and were not initially boxed.
There were fake ingots made of pewter, not sure why. I got a couple as examples and sent them to Bob Lemke who then included a description of them as fakes in the catalog.
It is complicated because there are some real pewter subjects in the run. They were premiums to dealers who sold so much product. There was only one player done in pewter for each year and they are listed in the Catalog
The fakes can be spotted by the division lines along their sides, as they were two pieces molded together
I can hardly believe I am writing this while parked on the Amazon River in Brazil in Santarem. We are on the backside of a 71 day Circle South America Cruise that started in Miami on 1-16 and ends there on 3-28.
