The tradition is both older and newer than this. As an example, in 1602 Samuel Rowlands produced a pamphlet poem Tis Merrie when Gossips meete, which included the verse
Well wot you Besse, to whom Ile drinke too now,
Sure as I liue, vnto your sister Sisse,
And to the Youth that did the Angell bow.
And sent it for a token : trueth halfe this :
He loues you both, vpon my word he doth,
Resolue it, or you wrong him Besse, in soth.
Here the Angel was a gold coin, twenty times more valuable than a silver sixpence but later the tradition was followed by poorer individuals, and bow involved putting a bend in the coin to discourage it from being spent. The later lines stated this was a love token.
