The Capitol Hill Vending Machine was a Dixie Narco DN 180.105-5, (c. 1980's?) that would, for 75¢, dispense a mystery beverage.
What makes it a cryptid is:
a) it sold non-US-market and discontinued beverages
and b) nobody knows who operated it. https://t.co/0zERZCrSj5 pic.twitter.com/t4SivcOxDR
Wikipedia:
Capitol Hill's mystery soda machine was a vending machine in Capitol Hill, Seattle, that was in operation since at least the early 1990s until its disappearance in 2018. It is unknown who stocked the machine.A drink could be chosen using one of the "? mystery ?" buttons and the dispensed drinks were rare cans, like those not ordinarily available in the US or cans that have not been in circulation since the 1980s. Examples included Mountain Dew White Out, a raspberry-flavored Nestea Brisk, a Hawaiian Punch, and a Grape Fanta. The locksmith in front of whose business the machine stood claims to have no knowledge of who operated it.
