10 Pesos Silver certificate, Eagle seal, With overprint

The Philippine silver certificates of 1903 were issued under the authority of the U.S. colonial administration following the Currency Act of 1903, which established the Philippine peso at a fixed rate of two to the U.S. dollar and created an entirely new monetary system for the archipelago. The Bureau of Engraving and Printing in Washington supplied the printed sheets; the overprint was applied to distinguish authorized issues from unissued stock, a precaution reflecting genuine concerns about counterfeiting and unauthorized release in a territory still under active military pacification.

Pick 27A is the overprinted variant within the series — the distinction matters because unoverprinted examples exist and carry different catalog values. Worth verifying which overprint type is present, as the series includes more than one.
