Such things can occur because of large differences in the number of unused coins in the vaults of National Banks. If country X has almost no spare coins left but needs them, and country Y still has loads of surplusses, then can agree to ship the coins from Y to X.
The letters on the notes are just neutral codes, not national symbols just like heads sides of the euro coins.
If those pooling coins are more widely used the original idea of the different coins of EMU countries is lost somehow.
