Coin Man

Can anyone tell me if these are a good grade and possible value

Ian, Mmany thanks for the information, much appreciated Mike

After many years of holding on to many old coins I have decided to sell them, having no one to pass them on to. I have an 1866 sixpence with a die number 40, in good condition. Looking on ebay there seems to be a huge variation in price from 99p to £200.00 +. Can anyone explain the reason for this. Thanks Mike
