One of my two allotments is an orchard which was planted in 1946. I took it over twenty years ago after many years of neglect. It now produces apples in abundance and I crush tons of the fruit to make juice for my family and neighbours. The nectar of the gods! A banknote collection can be all over the place but a bit of effort gets it into order and then you can decide what is needed to improve the collection and what can be sold.
