The Indonesian twenty five rupiah coin (Rp25) is a now-defunct denomination of the Indonesian rupiah. It was introduced in 1971 and was last revised in 1991. Coins of this denomination were minted until 1996 and have been invalid for transactions since August 31, 2010 when the 1991-issue Rp25 coin ceased to be legal tender.
The first Rp25 coins were minted in 1971 as cupronickel coins. They had a 20mm diameter, were 1.25mm thick, weighed 3.52g, and had a milled edge. Its obverse featured the lettering "BANK INDONESIA" and "25 RUPIAH" as well as two stars, while its reverse depicts an image of the Victoria crowned pigeon (Goura victoria) as well as the lettering "Rp25."[1] These coins ceased to be legal tender on June 25, 2002, and were redeemable in general banks until June 24, 2007 and in Bank Indonesia offices until June 24, 2012.[2]
The Bank of Indonesia revised the Rp25 coin for the second and last time on December 16, 1991, as an aluminum coin. It had an 18mm diameter, was 1.98mm thick, weighed 1.22g, and had a plain edge. Its obverse featured the national emblem Garuda Pancasila, the mint year (e.g., "1996"), and the lettering "BANK INDONESIA," while its reverse featured an image of a nutmeg plant (Myristica fragrans) as well as the lettering "Rp25" and "Buah Pala" (Nutmeg). These coins ceased to be legal tender on August 31, 2010, due to its extremely low value, which makes them undesirable for making transactions, and were redeemable in general banks until August 30, 2015 and in Bank Indonesia offices until August 31, 2020.[3] [4]
