Nothing special or super rare, but interesting nonetheless...
The US Mint at Denver struck the 1972 Piso coins for the Philippines. Over the years, I've seen a variety of errors on these coins. Maybe producing 121.8 million examples for the Philippines in 1972 stressed the QC process in Denver?
The coin's reverse features a left-facing portrait of Jose Rizal, a National Hero of the Philippines due to key role in the rebellion against the Spanish; he was executed by the Spanish for his role on December 30, 1896. The obverse presents the Coat-of-Arms of the Republic of the Philippines. (Sides appear opposite vs. expected in
NGC holder.)
1972 Philippines One Piso - Clip Error
Note: Clip percentages are generally determined via the weight of the coin. The weight of this coin is ~70% of that of a full planchet.
