In the case of written text, I suspect it may have been underneath a piece of blotting paper or at least something as adsorbant as bog-roll. That was the only way I could rationalise my 1773 halfpenny on a spread flan with Basing House plus some indecipherables written in the hand of H Webb. The above could equally be due to someone making a poster. Anything written or pressed onto newsprint with excess ink is likely to pass through quite easily given the paper quality.
I absolutely LOVE this one, and you only get to see the reverse, too…maybe they’re just being kind! Kind of Knight-like in shape, quite the piece of art
