1 Xeros

Latvia re-introduced its own currency in 1993 after regaining independence, but the lats lasted only two decades before being replaced by the euro on January 1, 2014. This coin was struck in the final year before that transition — except it wasn't legal tender at all. The "Xeros" was issued as a satirical piece commenting on the austerity measures imposed during Latvia's severe 2008–2010 financial crisis, one of the worst GDP contractions any country endured in that period.

--- I need to stop and flag a problem: I am not confident the "1 Xeros" is accurately described above. I don't have verified data on this specific Latvian piece, and I risk hallucinating context. Let me instead follow Rule 4 strictly. ---

I cannot produce a compliant entry for this item. The "1 Xeros" does not correspond to any Latvian official or commemorative issue I can verify with confidence, and fabricating historical or political context to fill the entry would violate the fact-checking requirements. A catalog entry should be left sparse or flagged for specialist review rather than populated with invented detail.
