Bi-metallic coins

[davidrj]

I quite like b-metallic coins, bit of a sideline collection. I save £2 coins and foreign ones from change when abroad

I've always considered Moore's model pennies to be early (1840) examples (I don't count copper plugs in tin halfpennies)

Just spotted these French patterns on Ebay pattern1 pattern2 - don't know the size but they look similar to the Moore's ones

So question is, what are the earliest examples,

as a pattern?

as a circulating coin?

tin farthings as they always had the plug. they should count really.

or the charles I farthings where they used other metals to fill in chips etc.

ever seen these euros?

copper band round the outside of the brass area.

I presume you don't mean things like electrum (gold and silver) which was used millenia ago in Greece?

I'm talking about modern ones like the £2, seem to think Italy had some in the mid 1980's

Suppose it was only recently that the production costs of making the blanks made them cost effective

can't imagine a circulating £5 coin is far off

technically the plugged tin farthings of the late 17th century.
