These notes were exchangeable at SAMA offices and used to facilitate transactions for the millions of pilgrims visiting Mecca and Medina. The 'PL' designation stands for 'Pilgrim'. This series was withdrawn in 1976 when SAMA unified the currency system. The serial number format and printing characteristics suggest this is from the third or fourth printing run of this design.

Port Victoria, the capital of Seychelles on Mah\u00e9 island, serves as the economic and commercial hub of the archipelago, with fishing being a cornerstone industry. The scene captures the working harbor with multiple vessels representing the maritime economy. The denomination appears as 500 (likely an overprint error on the image or a different note) with text 'YEAR OF SIENA LEONE' and 'FIVE HUNDRED LEONES' visible, which represents a mismatched pair with the front image.", "historical_notes": "The front displays a 25 Rupees note from the Central Bank of Seychelles, featuring trilingual inscriptions in English, French (implied by 'CENTRAL BANK OF'), and Seychellois Creole ('LABANK SANTRAL SESEL'). The imagery emphasizes the nation's agricultural and maritime heritage. However, the back image shows a 500 Leones note from Sierra Leone (not Seychelles), evidenced by the text 'YEAR OF SIENA LEONE' and 'FIVE HUNDRED LEONES'. This is a clear mismatch. The Seychellois rupee has been the currency since 1914, replacing the Mauritian rupee. Without a visible date or series information on the front, and with the mismatched back, precise dating is impossible.

The back is definitively from a Surinamese 5 gulden note issued by the Centrale Bank van Suriname, likely from the 1991-2000 series featuring Passiflora quadrangularis. The Surinamese gulden (SRG) was the currency from 1940 to 2004, when it was replaced by the Surinamese dollar at a rate of 1 dollar = 1,000 gulden due to hyperinflation.
