100 Lire Banca di Trento e Bolzano - 2nd type

The Banca di Trento e Bolzano was one of a handful of regional Italian institutions authorized to issue fiduciary notes — technically cheques payable to bearer — during the small-change crisis of the 1970s, when coin shortages became severe enough that private and semi-public issuers stepped in to fill the gap. The Bank of Italy tolerated rather than formally sanctioned these emissions, a legally ambiguous arrangement that persisted longer than anyone expected.

The "2nd type" designation marks a modified printing from the earlier 1976 emission, distinguished primarily by altered serial number formatting. These circulated almost exclusively within Trentino-Alto Adige.
