Value Banknotes and the Butterfly on the Door Handle

Yesterday, I saw this butterfly on the door of the summerhouse. In the light of the sun, the colour on its wings was nigh perfection. Beautiful. When you look through a collection of notes, the colours, the quality/grades can be so enthralling, at least to me. MY wife rolls her eyes when I speak of a new UNC banknote and its beauty. She keeps me on level ground!
