This coin is the first in Philippine history to have a hole. Due to its small value, it has been used as a washer, as earrings, and various other kinds of ornaments. The hole actually shaves off part of the production cost by requiring less metal to mint a coin. It also helps differentiate the 5 centavo coin from the 10 and 1 centavo coins which are similar in size.

I scoured a huge bank in my city and found only three of these coins. The rarest of the current coins in use, this denomination is hardly necessary but Bangko Sentral has to mint them because they are required by law.
