1 Piso BSP seal type 2

The BSP "seal type 2" designation marks a subtle but cataloged revision to the reverse hub used on this denomination, a change introduced without public announcement as part of routine die retooling. The Philippine mint has made several such incremental modifications to the 1 Piso across successive production runs since the New Generation Currency series launched in 2018, and distinguishing them requires close attention to the seal's inner detail rather than the broader design.
