The swaps will be made by postal mail under complete discretion.

      Here is the procedure :

You have found a banknote which I hold in double in my collection. (doubles are mentioned by a red star *).
-  This banknote interests you, contact me by e-mail with a scan of your swap. (I don't have to already hold in my collection your possible swap)
- I'll give you then quickly my agreement or not.

- Send back to me an e-mail for confirmation and I'll do the same.
- From reception of your banknote, I'll send you mine.

      Don't hesitate to contact me !
