Instructions
Place your coins inside individual mylar-lined cardboard folders known as 2-by-2s, and then arrange a group of 2-by-2s in a fitted tray, which in turn can be displayed under a glass-topped coffee table or cabinet. As of 2010, 2-by-2s cost only a few cents each from online numismatic accessories stores, while special 16-inch by 10-inch trays retail for just under $20.
Exhibit your most precious coins inside snap-lock holders made from nonreactive plastic. Retailing between $1 and $5 online, these can accommodate individual coins, pairs or whole runs and are available with colorfully themed backgrounds such as the US flag. Once again, arrange these within glass-topped pieces of furniture.
Achieve a more expensive look for individual coins by placing them inside a "slab," another variety of snap-lock case with a fitted interior and space for labeling, available for just under $2 online. Why not prop up a slab on your desk with a small easel or support so that you can enjoy your latest purchase while you work?
Hang small groups of coins on the wall inside special fitted and glazed frames, again available online. Alternatively, house your snap-lock cases in wall-hanging cabinets, retailing in the region of $80 from online display furniture stores.
Draw attention to the very finest pieces in your collection by placing them inside individual glass domes with walnut bases -- these should cost you around $25 as of 2010.
