What Size Air Tite Do I Need For A $5 Gold Eagle?

I like the serrated edges on the 2X2s.

I use ex British Royal Mint clear hard acrylic screw capsules, that were originally sold in proof sets and for encapsulated individual proof coins.

The sets get broken up by the dealer, and the individual coins are sold for a greater profit.

My coin dealer usually has them in a range of sizes to the nearest millimeter in diameter or thereabouts. The empty capsules normally cost me a dollar each.

Even the largest encapsulated coins can be stored in 2 1/2 x 2 1/2 album pages.

This sort of storage allows a viewer to handle each coin with out any fear of damage. Encapsulated Double Eagles can be handled by anyone with this sort of protection, even kids with stick little fingers.

Then again, you can always slab your more valuable coins, which is what most American collectors do anyway, and 12 pocket slab albums are available. It's just that I prefer not to have any coin slabbed, and screw capsules are cheaper.
