Trading? old Castilian/Spanish billon (also open to selling some)

Recently I have obtained a large lot of Castilian and Spanish coins most of which are billon and from the 13th to 19th century. I collect by KM or in this case AB and thus I have some doubles. I have added them to my swaplist and am looking to swap them but also open to selling them. In the image are also 5 German 1 pfennigs from the mid 1500s which i am also looking to swap/trade.
Other than that my trade list contains many silver coins including a few hundred Australian and world silver

Regards
Robert
