3 Euros First powered aircraft

Slovenia's 3-euro denomination was introduced specifically for commemorative purposes, sitting outside the standard euro coinage structure — the European Central Bank authorizes member states to issue collector coins in non-standard denominations, and Slovenia has used the 3-euro format aggressively since adopting the euro in 2007. This piece marks the centenary of the Wright Brothers' first sustained powered flight at Kitty Hawk on December 17, 1903, a date that fell six years before the coin's issue.

The 2009 date places it in a cluster of aviation centenary coins issued across multiple countries between 2003 and 2009, each staking a slightly different claim on the milestone.
