50 Sucres

The Banco Central del Ecuador was established in 1927 as part of the Kemmerer Mission reforms — Edwin Kemmerer, the "Money Doctor," swept through Latin America recommending gold-exchange standard banking structures, and Ecuador was among his clients. This note was issued under that newly centralized authority, consolidating what had previously been a fractured system of competing private bank emissions.

The American Bank Note Company held the printing contract through the full run of this series. ABNCo's relationship with Ecuadorian currency went back decades, and the plates for several denominations in this period were closely related in composition to earlier private bank issues from the same shop.

The watermark is the sole security feature — no color-shifting inks, no serial number varieties of note, no overprint complications recorded for this pick number.
