Coins are collected and saved in a box constructed from a box frame (1) extending around the peripheral edges of two parallel panels (2) to bridge the gap between them. Coins are added to the box through an opening (15) in the top section (12) of the frame. - One of the panels is transparent and the distance between the two panels is equal to the total thickness of no more than three of the thinnest coins to be placed inside the box. - (Dwg.1/1) |
