hi all i have recently become fascinated in coins etc since helping my mother sort through some rare coins she bought in a house clearance. las weekend i bought a large bag of assorted coins from a jumble sale weighing about 10kilos.over the last 10 days i have been painstakingly looking at each 1 and have to know if i have struck a beauty. there are several good 1p coins from apparently rare dates like 1882,1912h,etc etc also 3 tubes i opened of 1939 threepences,1941 farthings and various dates of halfpennies.many of the pennies have the letter h next to the date wich i believe is heaton mint ? the problem i have guys is i dont know yet as to what the grading is f,vf,ef,unc etc etc how worn makes them worthless and what is the minimum allowed to be worth anything. just a note to say i never would have thought i would have got into coins and collecting but all of it is fascinating me now. many thanks
