Noted numismatic author and specialist Mr. Fred Schwan has frequently listed his favorite Second World War collectible as the common Allied Military Currency (AMC) 2 Franc note.  To him, this note represents "history in your hands", as so many of these went with Allied troops on D-Day, to allow a medium of exchange for commerce.  These notes are fairly common and can be obtained in excellent condition for very reasonable prices, so it is not their rarity that makes them valuable; it is their connection to a tremendous event in history.

As I keep exploring resources available to me as a coin collector, I keep finding new things.  My latest find revolves around the LKNS coins I submitted to NGC for certifying.  NGC will take a digital image of your coin in its holder, so that when you go to ngccoin.com to verify the genuineness of an NGC-slabbed coin, you can see a picture of it after you enter the certification number.  You can also ask NGC to take higher resolution professional photos of your coins before they are slabbed, which is very nice for seeing surface details.  But once you have these nice photos, where can you show them off (as is natural for a collector to want to do)?There's always the Collections section here at money.org, but did you know you can also create a collection within the NGC Registry?  Not only that, if it falls within a certain category type, you can actually compete your collection against others' collections for fun and points... maybe even recognition.  I did not know anything about this... I'd heard of Registry Sets but didn't know much about the topic.Of course, not every type of coin that people collect are categorized.  Some won't be, but others just haven't been identified yet as an area of collectors' interest.  If you don't see the proper category for the type of set you want to compete, you can suggest it and NGC will consider creating it.  It's not guaranteed that they will, though.Your other option is to create a Custom Set.  It's not a competitive set, in that you don't win prizes or score points comparing your set to someone else's of the same type of coins.  But you do get to display it where other collectors can see it whenever they want.As of this writing, NGC has been updating their set registry pages.  While competitive sets are hosted on NGCCoin.com/registry, custom sets are still hosted at the old site, https://coins.www.collectors-society.com/wcm/CoinCustomSetListing.aspx.  Plans are to migrate the custom sets to the new URL eventually.I decided to try this out by listing my set of LKNS coins.  First I created a custom set, gave it a name, and added the coins using the NGC certification numbers.  Adding the coins brought over the photographs NGC took when they certified them.  Then I could fill in details, both about the set, and about the individual coins.  Check it out:https://coins.www.collectors-society.com/wcm/CoinCustomSetView.aspx?s=27929You can do this for your own sets of NGC-graded coins.  If you like adding details and telling background stories behind each coin or set, this format lets you do that.  Sometimes a good coin is better when the story behind it is known.
