I'd recommend starting with something like collx.app to scan the cards and get a rough sense of value. If it's past your threshold (say $50) then you can look into the pricing history a bit more. The best tools for that would probably 130point.com and cardboard.market. 130 point lets you search past ebay sales and you can get a sense of card value using that. Cardboard market lets you do that + look at the prices... Source: 11 months ago

You can use a tool like collx.app to scan each card and check how much they're selling for. If you want to look at graded copies for each card you can use cardboard.market to search up the card + the grade and see sold listings and also cards for sale to see where people are pricing.

I started using CollX, an app to helps me figure out how much my trading cards are worth. You should get it, too! Check out my collection and add yours. Use my referral code, NZ3SY, when signing up. http://collx.app. Source: almost 2 years ago

I wish I was into American fantasy sports so I could check how they build their websites and actually understand what is going on 😅 I found this website called sleeper.app which looks amazing and I think it sort of proves that it is possible to get people to switch their main platform.

FYI I'm pretty sure you can use Sleeper on desktop (it works for me at least, never used the mobile app). And agreed on the LEC quiz videos and Friday games. Source: over 2 years ago
