My brothers and I were obsessed with NFL cards growing up. It was mainly for the love of the hobby, but it gets expensive so you'd like to be able to make some of your money back. We realized how difficult it was to do that: you need a rare card, and it has to be in great condition, and preferably graded, and then you have to find a seller. We didn't sell a single card, ever. This was right when Ebay was starting so we weren't using it yet. After about 3 years of spending most of our money on cards, we moved on.
What I like about Top Shot is that it fixes most of those issues:
-There's no varying conditions, you can't "mess up" your card (fold/bend, get wet, tear, etc).
-This also eliminates need to get graded
-Every single "moment" is individually numbered, even the common ones that have over 15,000 in circulation. This adds a level of intrigue and value. So even in common packs, if you get a very low numbered common card it can still be very valuable.
-Centralized marketplace (same website where you purchase), it's fairly easy to sell.
-You can do everything on your phone or computer, you don't have to spend time driving to a store.
Of course, there's negatives. Mainly that it's currently very difficult to withdraw funds (can take 6-8 weeks). Also, the market could easily crash, although right now things are looking promising. And the whole not owning a physical product aspect. But with people being raised with digital pictures / books / currency, I don’t see this as a big issue.
I joined this thread because I never stopped liking sports cards. Now that I'm old and have more disposable income, I was thinking of getting back into cards. The stories of people waiting at the store to clean out stock really put me off though. It just happens that at the same time I was contemplating getting back into regular sports cards, Top Shots is starting to blow up. So, I'm in!
