I’ve got it in front of me now.
It’s a little smaller than a 50-cent piece. The heads side says “Augustus Pater” around the head, and the reverse has what looks like 2-column arch with fasces inside, with S and C bordering it on the outside, and “PROVIDEN” underneath.
It feels like metal and is heavier than a quarter, so I think it is metal, but I’ve never used it to scratch off prize tickets, so I can’t be sure!.
Just to be clear, Augustus Pater on the coin is in caps (as are all the letters).
I know lower-case came in later.
The use of base-metal coins for contests and promos was common back then, those were the days... there used to be a bunch of aluminum ones around here that Sunoco gave out for some sweepstakes or other, late 60s, perhaps early 70s.
