How much is a 1000 dollar bill from Spain worth?

Answer 1

Please check your bill again and post a new, separate question with the bill's date and its correct denomination.

Spain has never used dollars, only pesetas (up to 2002) and euros since then.

Answer 2

No, because the highest-value bill is €500. If you have a "€1000 bill" it's a fake.

Answer 3

No. The highest denomination is €500, and it isn't frequently used in ordinary commerce.

Other denominations are €5, 10, 20, 50, 100, and 200.
