I do have a collection of many things, some things I started to collect, whilst others I still collect or don't collect anymore (*cracks knuckles again tonight*):
Pokemon cards-I don't know why I bought these cause I never used them
Yu-Gi-Oh-Only bought a few legit packs
Stamps-Have only collected a few
Stickers-Had an album and box full of them...
...Until my sister found the box
Shells-Have a few jars and bottles full dating back 10 years ago
Coins-I still collect these every now and then-especially the several variants of commemorative coins that they release here in Australia Such as this, celebrating 100 years since the founding of Canberra:
I also have foreign currencies such as US Dollars, Euros, Singapore Dollars and Vietnamese Dong.
My grandparents also have a tin containing lots of former currencies, such as the Australian pennies for the old Australian currency and the original banknotes for the current Australian currency, as well as Italian Lire, Yugoslavian Dinar, and the oldest coins of the lot, about a dozen Austro-Hungarian Koronas:
Model cars-Has waxed and waned over the years. I would like to collect them but space to display them is a real issue for me at the moment. I would love to obtain an AutoArt model (especially the Gran Turismo ones)
Video game Collector Editions-A more recent one, starting with the GT5 Signature Edition. Since then I have about half a dozen more, the most recent being the Titanfall Collector's edition
I am also considering paraphernalia, mainly in the form of posters and (maybe) press kits
Gran Turismo paraphernalia-Another more recent one, with recent purchases including the GT6 Collector's Pack (Asia Exclusive 15th Anniversary Edition) and Gran Turismo Tomica Car Set (I have a long way to go, and have my eyes on demos and Press Kits)
Adventure Time Comics-A couple of months ago I decided to buy one of the spinoffs to the main series (which consisted of 6 issues). Loved reading them (haven't been a massive comic book fan until now) and am considering getting more of them (including limited edition/exclusive prints)-the only downside is that I have to get them from America (as they don't sell them here in Australia-not that I've seen anyway), which means my wallet is effected by the postage and handling costs
Edit-Didn't realise until I posted that this was a dead thread for over a year!
