Hi i'm DiskOfReturn and i've been collecting for about 5-10 years now. I'm collecting for the purpose of collecting but also occasionally for profit.
My goal is to reach 160 item stacks above 100k so i can fill my whole screen with them in 1 bank tab. Besides this i also collect (semi) discontinued items, common mats and tokens, i roughly have about 30k tokens. I don't have an endless amount of gp so i always choose what to work on (tokens/sof th items OR discontinued items OR 100k+ stacks) and just go with that for a while untill i choose something else. I first started to collect empty vials and soda ash due to their low pricing.
I recently finished my first wearable green stack of 10m steel darts.
If you want you can add me to the meet the collector list. My bank is a mess but here is the collection so far (leaving the tokens out for now):
