More Coins!
Even in antiquity there were various ways, both official and unofficial, to make more coins or to try to stretch the metal of existing coins further.
Coins 3 & 4 show an unofficial process called 'clipping' where the outside of a coin was 'clipped' to get additional silver to make more coins or other objects like jewellery. Coin 5 is an example of 'debasement' where the silver content of coins was deliberately lowered due to shortages. It was common in the 3rd century AD and caused many economic issues for the Romans.
