Okay like everybody else I'm looking for a valuation.
All are unused. Been sitting in a safe place all these years. All were purchased on this site.
Short answer for the 420:
a lotI think the mentioned prices are a bit low, but would be good if you are after a very quick sale
Some multi color leafs have sold for well above 1k within the last year or so, that does not guarantee that yours would, but I would likely start there. If you do not need to sell them urgently I would suggest listing a few times and maybe lower the price if you have to
I don't think 600$ on the old single shot MX skulls is a bad price, but likely a bit under what you could get with some effort. There have been a few Vader caps for sale the past year or so, and I believe they have gone between 1 and 2k. Yours does have the added benefit of the cool Vader sack, but I'm not sure what that does for the price.
For the Oktoberfest, I would guess around 5-600$ to start as some Topre ones have moved in the 3-400$ range fairly recently.
