The sheer number of signature combinations on P#187 reflects real political turbulence compressed into a short window. The 1998 watermark shift — from a single portrait to two portraits mid-run, both under Ramos and Singson — is an uncommon mid-year change that created distinct varieties without any formal announcement. Then Estrada's 1999 signatures arrived, followed by his removal from office in 2001 and Macapagal-Arroyo's succession, meaning this single pick number spans two presidential impeachment-era transitions.

The red versus black serial number variants under both the 1998 Ramos/Singson and the 2001 Macapagal-Arroyo/Buenaventura issues add further collecting granularity — minor production decisions that now define separate catalog entries.
