<prompt> Human: I cant really go into the specifics, but I came across a one of a kind item at a thrift store and was offered a sizable amount of cash. Everything was legal, but I have no records of the transactions buyers wish. I want to invest it but Im afraid something bad is going to happen if 100,000 appears out of nowhere. What should I do? I cant tell my parents about this either. EDIT: theyre cameras. I volunteer at a thrift store and found an awesome collection of cameras. Im sorry it sounded so sketchy :Assistant: This whole situation sounds incredibly sketchy.Human: Sorry - I didnt realize how sketchy this came across. I love vintage cameras and someone dumped a HUGE collection of rare and pristine medium and large format cameras as well a few first edition nikon rangefinders. Seems like someone didnt know what they were worth  <response>: I imagined this was something like this and not drugs or something. I think you should report the gains and pay taxes on it or put it in a safe and pay expenses off it for several years.
