Anything less than 50p and i dont use it. Dont really like touching coins (odd phobia

) and i hate having a pocketfull of change.
I also find it annoying when people stand at the counter and start counting out their 2p-20ps to buy something at 2 or 3 pounds. Count it before or come prepared with bigger money !
Also,more on topic, When i was younger my mum used to keep any change in a box, and then every so often sort it and bag it, and then take to a bank to change it for notes etc
