This is a Royal Canadian Mint box meant to hold the 2018 20th Anniversary Silver Maple Leaf, and the 2019 40th Anniversary Gold Maple Leaf 1oz coins. It is very well made, and the felt lined tray can be removed. There are slots such that the coins can stand upright, or lay flat. It is 22cm in length, or just under 9 inches
It was sent to me by a coin dealer by mistake, and they told me to just keep it rather than send it back.
Free to anyone willing to pay for your choice of postage. I'm happy to post internationally, but the postage is expensive.
