How do you currently figure out what your sneaker collection is worth?

One thing I’ve been thinking about while building SOLE’D:

How do you actually figure out what your sneaker collection is worth?

It seems like there’s a lot more to it than just looking up a sneaker’s name, when the condition, release year, version, size, etc. can all change the value. I built SOLE’D to try to take that research out of the process by letting you scan the physical sneaker and estimate its value based on the specific pair and its condition. Curious how other collectors do this today. Do you manually look up every pair, use a spreadsheet/app, or mostly just go off what you paid for them?

Would genuinely love to hear how you guys do it.
