An outstanding Matching Radar Serial Number Pair featuring the identical serial H75788757B across two consecutive series — the 1977 (Fr#1909-H) and 1981A (Fr#1912-H) St. Louis Federal Reserve Notes. Both notes are certified by PMG, graded 65 Gem Uncirculated EPQ and 66 Gem Uncirculated EPQ, confirming exceptional paper originality and superb eye appeal.

Radar serials — palindromic numbers that read the same forward and backward — are among the most sought-after fancy numbers in modern U.S. currency. This particular pair is even more remarkable, as both notes share the same radar pattern across different print years, a rarity made more impressive by their high-grade condition.

With bold embossing, bright paper, and vivid green Treasury seals, this cross-series radar pair is a premium addition for collectors of fancy serial number notes or PMG-certified modern U.S. currency.

Background Information

Radar serial numbers are a subset of fancy serials valued for their symmetry and rarity. Matching radar numbers across multiple print series are extremely scarce, particularly when both examples survive in Gem Uncirculated EPQ condition.

These two notes, printed for the Federal Reserve Bank of St. Louis, represent consecutive eras in U.S. paper money design — from the late 1970s through the early 1980s — under the signature combinations Morton–Blumenthal (1977) and Ortega–Regan (1981A). Both issues were printed by the Bureau of Engraving and Printing (BEP) and certified for originality by PMG.
