Before sending of my hoard of recent Spanish banknotes to the bank to be destroyed forever (and get me some cash for my collection!), I'd like to offer them to fellow Numistans to increase your collections. I'm offering them at exchange rate (€6,01 or $7.3 per 1000 pesetas) + €3 for worldwide P&P.
Let me know if you want any of these, even better if I could swap them for some of your current local currency!

I also still have a few for sale that will not go back to the bank, as their value is a bit higher, but can be combined with some of the above:

5000 ptas (1976) https://en.numista.com/catalogue/note205299.html €40
5000 ptas (1979) https://en.numista.com/catalogue/note205251.html €45
1000 ptas (1971) https://en.numista.com/catalogue/note205693.html €9
500 ptas (1971) https://en.numista.com/catalogue/note205700.html €10
