I think a lot of newer or casual hobbyists donāt know anywhere to look but eBay, so their perceived rarity is based on whatās available to them on that platform. Which stinks because Iāve seen CAC swirls that would likely only fetch $200 tops as a 9.9 mint on Block sell on eBay for $300-$400. Iāve seen quite a few Germanās sell as CAC guineas on there as well.
I kind of have two opinions about it. I love going through old marbles, like a jar from the goodwill, and seeing what I can find. I donāt care that theyāre scratched or chipped or imperfect, I just love the hobby and seeing the different types, especially if I find one Iāve never seen and can learn something new. I also donāt mind paying top dollar for a really stunning example. But what I refuse to do is pay hundreds of dollars for a marble thatās not truly mint condition or close, and/or really really stunning. Sadly, like all things, I think the crowd of flippers have seen opportunity in marbles and the people who appreciate them, and they are using eBay to sell regular common marbles at premiums.
