Why do manufacturers of accessories for collectors make trays and boxes for round coins with both square and round compartments? Why not stick to just round ones? After all, coins are round…
This question is often asked even by those who have been collecting coins for decades. The answer is actually quite simple: aesthetics and ease of use. Both round and square compartments have their own advantages.
A coin — especially when it’s in a capsule — is easier to handle when placed in a square compartment: a round object is easier to remove from the corner of a square slot than from a perfectly fitting round one.
Moreover, there’s often a need to store coins of different diameters in the same box or tray. In such cases, square compartments are preferable, as coins of various sizes tend to look more visually balanced in them than in round compartments.
So when is it better to use a box or tray with round compartments? Only when all the coins are of the same size and their diameter matches the compartment exactly.
