10 000 Pesetas Institut Català del Sòl

The Institut Català de Sòl — the Catalan land agency — issued this note not as circulating currency but as an internal accounting instrument tied to land transactions and cooperative housing schemes administered under Catalonia's newly restored autonomous government. The 1982 date places it squarely in the post-Franco transition period, when Catalan institutions were rapidly reconstituting themselves under the 1979 Statute of Autonomy and experimenting with quasi-financial instruments outside the Bank of Spain's direct purview.

Whether these functioned as vouchers, bearer bonds, or internal transfer documents remains a matter of some debate among Spanish notaphilists — they circulated within a closed administrative system, not among the general public.
