Here the last trial strike of the 1967 - 72 issue of the Marcelo H. Del Pilar 50 centavos. The design was discontinued and the BSP has not produced post 1972 fifty cents until 1983.

Pagkatanda ko ay ganyan na ganyan ang mangyayari kapag nilubog mo sa muriatic acid ang mga pera noon na gawa sa nickel at copper.

Dear Sir,

The normal coin is not clad but an alloy of copper and nickel. If you'll dip or put it in acid, you'll never end up with a copper coin. The acid will automatically attack copper, silver, and nickel that would result to corrosion. Gold and platinum meanwhile can resist acid attacks. Therefore, even if the coin is clad nickel or copper-nickel, you may never strip down the coin because acid will automatically penetrate both the layers resulting to uneven surfaced coin.Thank you for viewing.
