Vintage

Vintage quality has no functional difference whatsoever, and was simply given to many items when the Mann-Conomy update dropped on September 30, 2010. The reason why these were given is because the mann-conomy update changed the way trading and marketing items works, so all preexisting items got the vintage quality. There are some considerably rare vintage items, such as the Vintage Ghastlierest Gibus. These are rare because they were not supposed to become vintage, or were simply already exceedingly rare items at the time of the update.
