50 Euro Cents 2nd map

Greece joined the eurozone in 2001, two years after the initial eleven member states, having initially failed to meet the Maastricht Treaty's convergence criteria on inflation and deficit. The "2nd map" reverse — introduced across all eurozone nations in 2007 — replaced the original design that showed only the fifteen pre-2004 EU members, an omission that had become politically untenable after the bloc's eastern enlargement.
