Can't remember who said it out here, but it was something like "one day we'll just trade digital pictures of coins with each other." Well...one step closer http://www.coinnews.net/2015/01/29/pcgs-introduces-digital-coin-albums/
That's cool. Aren't there some other (free?) options for non-PCGS coins? Edit: maybe this is what I was thinking of... http://www.davidlawrence.com/CollectionManager/
eBay goes to the next step, you can create "Collections" which are groups of other people's for sale items, and treat it as a collection you can show your friends. You only need to have found the picture on eBay.
