I have been going through some misc albums and stock and have found some World FDC, Australia, Israel, Ceylon, Spain, Japan, all from the mid-50's to mid-60's. I can catalog the stamp as used/FDC but would like to know how to value them. All are cache, some with special postmarks. (I'll post pictures later). I know Scott values FDCs of modern era postmark 1970 forward minimally, but was wondering (other than ebay) if anyone in the SCF community collects WW FDCs and has a sense of value on World FDC items
