Searched and Searched for Waffels, but...

Ok, I'm too new at this to know if your serious or not...but it does take a long time to get my coins back from NGC, so now that I know the reason, I wanted to see for myself what all the waffeling is about...! I did the eBay search, now I suppose you're laughing right, no matter how many times I did it or what configuration of key words I used, I kept getting the same 7 listings. Now I'm convinced I not only know nothing about collecting coins, I don't even know how to do a simple search on ebay...Honestly though, as excited as I am to get the results back from NGC, it's usually worth the wait. I still want to start a collection of military or war coins. After looking into this it's obvious I need to set some perameters because of the variety of commemoritives and so on out there. Can anyone give me a jump start on what would make a sensible and meaningful set to start with. Thanks!
