I have many CC for swap. My double list may not be perfectly updated, but it could give you an idea. Anyway, I'm up to date with most euro issues, except for a few ones (Erasmus, and a few of the expensive ones).
You can ask for different dates for the Spanish coins. Regarding commemoratives, I think I have more doubles, but this is a good list. You can ask for several units for most of them :
Spain 2011 CC rolls (Alhambra). Loose coins available too. Spain 2010 CC rolls (Mosque) Córdoba.
Spain 2009 EMU CC rolls
Spain 2005 Quijote (Quixote) CCs
