Today I organized a concert and after it took the proceeds from the cupboard.
I had two packs of coins: ~20 CROWNS and 50 Canes Venatici.
I divided the coins by 10 per pile.
After make piles to 50 they began to disappear (i mean piles). After repeating this action my CROWNS desappear and i have only 30 coins of Canes Venatici now...
