Well I collect Magic Cards, Star Trek cards, and Babylon % cards though none as actively as I used to.
I have a collection of Anaimaniacs merchdise including:
Yakko and Dot pillows (Still need Wakko)
Three figurines of Yakko, Wakko, and Dot holding hearts from valentines chocoloates
Every Happy Meal toy made during that promotion
Most of their episodes on tape
Pinky and Brain floppy disks
Pinky and the Brain puzzle.
Dot keychain
I am lookinng to expand. 
Tell me about it! I ordered a Shiloh Sharps 1874 several years ago. It took a year after I ordered it for it to be delivered. I could have picked up an Italian copy for about half the price, but I liked the idea of owning an “official” copy of the famous rifle that was hand-made. So after waiting a year, I had to fork over $1,500… and I was flat broke at the time! Ow! My aching credit card! I still haven’t fired it or even put a round in the chamber. It really is a beautiful piece.
My SO collects old (“antique”) computers. See http://www.unnamedpcmuseum.com
I collect fish. Much like the story of the aunt with owls, I like fishy knick-knacks, and had a couple, so now every single person I know buys me fish stuff for birthdays and Christmases. Consider yourself warned, Pammipoo.
I collect cartridges. I’ve let it slide for a few years (too much other stuff going on), but I have a fairly sizable collection. Most is displayed in 3 old printer’s type trays, velvet-backed and glass-fronted, hanging on the wall. My particular areas of interest are the pre-1920’s, with emphasis on the early rimfires and the British big game period.
fscinating hobby.
As a child, I collected snowglobes from places where it doesn’t snow. It all began with a Sacramento snow globe, and it grew from there.
I have a thrift store art museum. My house is filled with original art. How many college kids do you know with oil paintings over their toilet? I pick them up for two or three bucks a piece. I kind of like the anonyimity involved. Some of my pieces are really compelling. Others (like those assigned to the bathroom) are somewhat less pleasing.
I have a fairly large comic book collection, most of which were acquired in the early eighties. Many are worth quite a bit, having been read once and then packed away in sleeves.
My current love (besides Lola) is fountain pens, one cannot help but appreciate the workmanship that goes into a well made pen. They are the only pens worth writing with.
Cocktail shakers. I don’t drink, yet am completely obsessed.
Frogs. Unfortunately, I started this collection around the age of 10, and it has followed me. How do you explain to your Great Great Grandmother that you stopped collecting the little green guys years ago?
Classic Punk Records. I have over 250. It sucks to move these. They’re fragile and they weigh a ton.
Fabric. I love sewing, so I pick up random scraps of fabric all the time.
Purses and Handbags. One for every outfit, and a few to spare.
Andrew Lloyd Webber cast CDS. Over 500 in 18 different languages. Such rare items as the Russian Jesus Christ Superstar, Hebrew Joseph, Danish Evita, Norwegian CATS, Mexican Starlight Express, all THREE Japanese Phantom of the Opera CDS, all 3 German Sunset Boulevard CD-singles, songs in Hindi and Finnish, and a lot of other stuff.
I am looking for the Norwegian Tell Me on a Sunday and the Japanese Phantom CD-single if anyone happens to have them.
Antique bookmarks, well it used to be a collection. I had about a dozen. Four of them were true antiques, the rest were old, but not antique, or they were unusual in some way. One my brother sent to me from Japan when he was working there. Sadly, they were stolen when our first home was broken into. I have two left. They were being used and not in the shadow box that was stolen. The two I have left weren’t ‘real’ antiques. My mom had said when she gave them to me that she knew they were imitations when she bought them, but she wanted to get some I would use instead of just admire. Someday I’ll have a collection again.
Using a post-it note for a bookmark today,
Abby
Single serving sugar packets…like the types you see in restaurants, all over.
My international collection contains over 500 unique packages.
Studi
Movie stubs. The ones with the name of the movie printed on it. I’ve got close to a hundred in a drawer somewhere, but only eight in my current stack, three of them for the same movie. Been a bad year for Hollywood so far.
-Scatter boxes. Those small boxes that really have no useful purpose except maybe to hold a few pieces of jewlery. I have about a dozen at the moment. Among them are silver, alabaster, a woven straw one from Russia, a little wooden treasure chest and a brocade covered one.
-Books on Egyptian history, even the weird stuff with little or no basis in fact. My oldest one is from 1918.
-Not intentional, but just seemed to happen with the classes I was taking, books on Human Sexuality. Not text books, but not those silly Cosmo type books either. Well researched texts. I have almost 2 dozen in two years.
-I used to collect unicorns, but my daughter slowly took that one over, as well as the dolphin collection.
-Madame Alexander dolls. I have about 30. Not the newer ones that they started making after Madame herself died, but the ones the company produced when she was alive and are now retired or impossible to get. They’re worth a small fortune at the moment, which is why they reside, carefully packed away, at my mother’s house so no one plays with them.
I have the world’s largest collection of sea shells. You can see my collection on the beaches of the world.
(Okay, so I stole that quote. I really do collect stuff. Like dust. And concert tickets.)
I have a collection of Yixing teapots, about twenty or so, but have called a halt to the collection (they’re a collection rather than an obsession!) To see what they look like and to read a very short history, check out this eBay auction:
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1247665035
The eBay item shown is actually too bright - I prefer the purple/gray pot
Also collect Xing warrior reproductions – have about eight of them. There are about 7000 warriors in Xing, China, but I doubt that I’ll collect more than twenty. Am going to China next year and hope to buy a few at the Xian site. I have one that is about three feet tall outside my front door (a General) and a few smaller and lesser warriors and a horse scattered around. You can view these guys at the following site:

I don’t really collect books; I amass them. When they fill the bookcases (about 1000 books) I have a first-come/first-served giveaway for people that I work with. Those that aren’t selected, I donate. I swap mysteries at a used bookstore.
I used to collect more but after hearing George Carlin’s take on “Stuff” I’ve become more selective. Only collect things I genuinely love.
I left out the several hundred matchbooks in an old institutional size Folger’s Coffee tin.
I collect toy ambulances
I collect clocks. they all run too (spend a fortune on batteries though!) my favorites are my kittycat clock ('member those) and my backwards running clocks.I also have a s**t load of Mad Magazines that I seem incapable of getting rid of,oh this is getting embarrassing, I’d better go…
1950s science fiction movies
Old software (DOS 1.1, for instance. I haven’t been able to find 1.0)
I collect road/street maps, especially old ones from the 40s and 50s before the Interstate System came to be.
My SO collects old postcards, especially the kind that were printed on linen card stock during the 30s, 40s, and 50s. He also collects almost anything that is Fort Worth related (i.e., books about Fort Worth, vintage promotional items from Fort Worth businesses, etc.) because he grew up here.
Antique sewing machines. Currently residing with my ex-SO approximately 3500 KM from here.
Last time I looked, I had 7 old cast iron ones, from the 1800s. Singers, and a Minnesota. Beautiful gold paint decoration on a couple of the singers.
