Three bank coin weights, £1 in silver, £5 in silver and £10 in 50p, from the 1960's,and 1970's

I have tested the £1 and £5 weights, and they are accurate for shillings, florins, half-crown's, and the Original 5 and 10 New pence coins.

I don't have enough old style 50p coins to test the £10 in 50p weight. 

They all have a functional screw opening on the base to allow calibration via lead balls.

the scales and the coins on the scales are not included in this listing.
