1 Xeros

I'm not aware of a coin called "1 Xeros" issued by Estonia in 2010. Estonia's circulating coinage in 2010 consisted of the final kroon series before euro adoption in 2011, and no denomination or series by that name appears in standard references.

I won't fabricate historical context for a coin I cannot verify exists. Please check the coin's source data — the name may be a transcription error, a fantasy piece, or a token outside standard numismatic catalogs.
