10 000 Reis - Pedro IV Overprint on P#13 - John Prince Regent

This note belongs to a fiscally improvised moment in Portuguese monetary history. When Pedro IV briefly held the throne in 1826 before abdicating in favor of his daughter Maria, the Royal Treasury needed to update existing note stock without commissioning a new print run. The solution was an overprint — a pragmatic and relatively common expedient for the period, but one that makes provenance and condition assessment particularly demanding, since worn overprints can be mistaken for forgeries or vice versa.

The underlying note, P#13, was a John Prince Regent issue from the earlier constitutional period. Layering Pedro IV's designation onto circulating stock of his own father's notes carries an accidental dynastic irony that no one at the Real Erário was likely thinking about.
