1 Lats Christmas tree

Latvia's 1 lats circulation commemoratives were an unusually successful public engagement exercise — the Bank of Latvia issued a rotating series of themed coins intended for everyday use, and Latvians actively collected them from change. The 2009 Christmas tree issue was released ahead of the holiday season as part of that ongoing series, which had built a genuine following since its inception in the early 2000s.

Latvia joined the eurozone in 2014, retiring the lats entirely. These circulation pieces became instant keepsakes overnight.
