I was kindly given by my friend's boyfriend a box of coins he got from his Uncle years ago, I've gone through this box of coins and so far I have these dates to swap. If you want to see photos then ask about the specific dates you are wanting. There are no very terrible condition ones with the exception of pre 1920 halfpennies and pennies although if you need the year you might just like them to fill :)
