What about the 2005 Mew stylus
I bought this because it was genuinely funny in college, for around $70 USD from yahoo auctions. I didn't realize it was rare and notorious till the auction ended, and then saw the last time it sold on ebay was in 2016 for $300. I now know this is on many people's holy grail lists, and I haven't seen it listed or sold anywhere since. I'm planning to liquidate my pokemon collection in the near future, but I don't know how/where to appraise this or gauge keeping it since it's not TCG. I also have another one that's strange, which I've been unable to find anywhere else online (last picture).
Is this something I can hold out on, till some kind of miraculous specific collector comes along? Does a myth surrounding a piece of merch like this keep growing? Or should I just throw it out on ebay and see what happens?
