This series used the Optima typeface. ₱5 coins were reintroduced in 1991, and reduced-size 25-sentimo, 50-sentimo, ₱1 and ₱2 coins were distributed starting Dec 1992. Production of 50-sentimo and ₱2 coins ceased in 1995. The series was demonetized after January 2, 1998. The Flora and Fauna series had an error for some coins, in 1983. The text for 10 centavos for scientific name of the Philippine goby was "Pandaka pygmea'" instead of "Pandaka pygmaea" and the 50 centavo coin for the Philippine eagle was "Pithecobhaga jefferyi" instead of "Pithecophaga jefferyi".

It has the profiles of Andres Bonifacio and Apolinario Mabini in a con-joint or in tandem manner on the obverse side. The reverse side bears the seal of the Bangko Sentral ng Pilipinas which is consistent with the common reverse design of the other six denominations. This has been an additional denomination to the current coin circulation and a replacement for the 10-piso NDS banknote. The series used the Optima typeface. The 1995, 1997 and 1998 5 peso coins had no mint marks, but coins issued from 1999 onward had mint marks. The 1995, 1997, and 1998 coins (with no mint mark) were minted by the Royal Canadian Mint. However, not all 1997 and 1998 coins were minted by the Royal Canadian Mint, quite a few were minted by the BSP (with mint mark).
