Foreign Exchange Notes [solved]

Is there a reason that foreign exchange certificates are considered “exonumia” despite having being pegged to the local currency and were issued like banknotes by whatever banking authority was in place at the time?

Additionally, they are not treated as exonumia by various references that catalog paper monies.

Hello,

Many foreign certificate exchange certificates can only be used under specific conditions and are not intended for general use. 

For example, N#302264 could only be used at designated places.

And N#222580 can be used only once and won't enter general circulation.

These limitations drove the choice to consider them as exonumia.

Do you have other examples in mind, which usage be closer to regular banknotes?

I guess I'm confused as to how N#209143 is considered exonumia but other Forum-Schecks in the same series (just higher denominations) are not.

I do think the other notes should be considered exonumia since they aren't “local" currency.

Hello,
I re-categorized the other forum checks as Paper exonumia > Foreign Exchange Certificates.
These notes were used by East Germans only for buying western goods in special shops (Intershop).
