I might have a few from some trade threads that have a little age, but from my own purchases it's possible there is a small number that are a few years. The bulk is from Nov '22 through current. CBid got a fair amount of orders for around 6 months so many of those are 12-18 mos now. Still bought/buying occasionally from CBid but the variety on CBid has become mostly redundant or stuff I don't want. I've bought around the net for the past year for added variety.
I am not aging in any strict sense, but holding most of what I buy for a year+ is what I hope to maintain as SOP.
