I have some key dates or high grades raw Canadian coins from cents to dollars. I usually store not so expensive coins in 2X2" holders. But how should I store those expensive ones? Should I store my RED cents in 2X2? I had tried the Air-Tite holders, but don't really like them as they are in round shape. I was looking to get the Intercept Shiled 2X2, but they don't make sizes for Canadian coins.
How do you guys store? Thanks all!
