In my experience, it really depends on if you just want to keep these coins in your collection forever or some day you want to sell them for the best price. Keeping the Box and COA retains or enhances the sell value. That's just the way it is. When these coins go up for sale on eBay, not having the box or COA cheapens the sell price everytime. Selling them locally may not make a big difference, but to a coin shop and eBay, it does. "If the coin (or set of coins) you're considering buying isn't listed in the Greysheet, you might want to reconsider ~ and for the Greysheet values to be valid for your coin(s), your coin(s) must be in the original box or packaging, with the original papers that it came with when it was originally sold by the U.S. Mint. Without the original box and papers in nice condition, the coin(s) will bring less than Greysheet prices. (Original boxes and papers are for things like proof sets, mint sets, commemorative coins and sets, US Eagle bullion coins, etc.)" http://www.coinbidders.com/warning.asp
Howdy, I've got a subscription for 5 of the silver proofs and I've got to go pick them up tomorrow. One for me, one each for the grand kids and two for giggles. I also just bought a roll of ASE's from provident. Most of the other annual world issues, I've already gotten as soon as they went on sale. Koala, Kook, Leaf, Panda, Britannia. Still waiting on the 13 Libertads and Philharmonics. peace, rono
