10 Diners Chichen Itza in Mexico

Andorra's extended series of world heritage silver issues, of which this Chichen Itza piece is one entry, was produced largely for the collector market rather than circulation — Andorra adopted the euro for everyday transactions in 2012, but had long relied on Spanish pesetas and French francs before that, issuing its own coinage almost exclusively as a numismatic revenue stream. The Diners denomination existed in a legal grey area for decades, never fully backed by a central bank of Andorra's own.

Chichen Itza was designated a UNESCO World Heritage Site in 1988 and named one of the New Seven Wonders of the World in 2007, which prompted a wave of commemorative issues from non-Mexican mints between 2007 and 2010.
