Postal Order - 50 Pence England

Post Office Counters Ltd was established in 1986 as a subsidiary of the Post Office to manage retail counter services, and postal orders remained one of its core instruments — a payment method that had survived largely unchanged since the Post Office (Money Orders) Act of 1838. By 1999, postal orders were already fighting obsolescence against bank transfers and early online payment infrastructure, yet remained genuinely useful for unbanked customers and child allowance payments.

De La Rue's involvement in postal order production gave the series security credentials well above their modest face value. The watermark on this issue is the primary — and essentially only — concession to anti-counterfeiting at this denomination.
