A mate of mine goes fossicking for gold with a detector. Two weeks ago he came home with what he thought was a threepenny coin, commonly called a tray. On close inspection it was in fact a fourpence coin or commonly called a "groat". I have since found out about and actually seen a twopence coin, a one and a half pence coin and a quarter farthing coin. I never knew they existed. These coins were actually used in England. Has any one else heard of these or know of other old English coins? Apart from the half crown and crown.
