[QUOTE="ddddd, post: 8407334, member: 22377"]We are back with another in this long running series, Latvia and the first "Coin of Time." From the website of the national bank of Latvia I have copied over their description (saved here in case the webpage linked ever goes down). [URL]https://monetas.bank.lv/en/coins/coin-of-time[/URL] [I]The Bank of Latvia is launching a unique bimetallic Coin of Time whose central part struck in hazy bluish metal niobium is enclosed by an outer silver ring.
