25 Dollars - Elizabeth II Grande Prêmio do Brasil

The Grande Prêmio do Brasil, held at Interlagos in São Paulo, has appeared on the Formula 1 calendar almost continuously since 1973. The 2017 race — the specific edition commemorated here — was won by Sebastian Vettel, though Lewis Hamilton clinched that year's championship at the same event despite finishing fourth.

Solomon Islands has no connection to Brazilian motorsport. The island nation is simply one of several small sovereign issuers that license their minting authority to bullion and numismatic program producers, in this case almost certainly struck by a European or Australian contractor.
