2 Reais Ayrton Senna

Issued the year after Senna's death at Imola on May 1, 1994, this commemorative was authorized by the Banco Central do Brasil as part of a broader series honoring Brazilian cultural and sporting figures. The timing was deliberate — the coin entered the market while public grief was still acute, and demand from non-collectors drove premiums well above face value almost immediately.

KM#643 is occasionally confused with a later Brazilian silver issue in the same series, but the Senna piece remains the strongest seller of the group by secondary market volume.
