Yes, we know it’s a bit odd that a magnet company should be talking about the size of coins, however, we often get asked for magnets “about the size of a £1.00 coin”. We also use a 50 pence coin in a lot of our photographs for scale purposes, so it seemed a good idea to measure a selection of UK coins so that we know what sizes they are!
Unusually, Liese had seven of the eight different valued coins in her purse instead of the usual moths so we’ve used these!
We’ve used our digital calipers to check the diameter (or approximation of for the 50 pence and 20pence) and thickness of the coins and these are the results:
| COIN | DIAMETER |
THICKNESS |
| £1.00 | 22.4mm | 3.1mm |
| 50 pence | 27.3mm | 1.75mm |
| 20 pence | 21.2mm | 1.75mm |
| 10 pence | 24.5mm | 1.85mm |
| 5 pence | 18.0mm | 1.75mm |
| 2 pence | 25.9mm | 2.05mm |
| 1 pence | 20.3mm | 1.6mm |
