The copper's probably worth more than that...... they used real metal in those days....
Contrary to colloquial terminology, coppers, that is old pennies, strictly speaking, aren't.
In the 20th Century they were actually bronze, which although 95% copper is far harder than pure copper and more resistant to wear in circulation. The tin portion of the bronze was increasingly replaced with zinc as tin got too expensive.
Old halfpennies weighed 5.67 grams and todays copper price is £5,588 per ton, or 0.558 pence per gram
That makes an old halfpenny actually worth about 3.2 new pence in metal today. Just to confuse matters, old pennies do not weigh twice as much as an old halfpenny, they come in at 9.4g or worth 5.25p
My life savings is just over 4 old shillings at face value, but they are 11th Century Norman pennies in as struck condition, so they are worth slightly more than 5.25p each, I hope.
