100 Pesetas - Juan Carlos I Last Peseta

Spain's peseta ceased to be legal tender on 28 February 2002, making 2001 the final year of issue for the entire denomination series. This particular type earned its "Last Peseta" designation officially — the Banco de España marketed it as a deliberate farewell to a currency that had survived since 1868, outlasting a monarchy's collapse, a civil war, and four decades of Francoism before dying quietly to European monetary union.

Most examples reached the public through collector sets rather than circulation, which accounts for the near-universal mint-state condition encountered in the market today.
