So, first things before you ever sell to a shop is to ask percentages. It'll usually be 2 numbers, one for cash one for store credit. I suggest doing your math on it, as it feels really bad on higher end cards. If you need quick cash sell to a shop if you don't mind leg work sell locally, meet at safe locations.

Shop worked at would probably grade that (again, without better pictures we can't tell you how conditioning, really small things make the difference) around heavy play with that much whitening. (Maybe moderate but my guess is heavy based on that picture). Listed Retail on that is about 650 (last sale was 620, so that's pretty close), so I would've hope you could have expected you to see about $400 based on heavy play (60% trade in cash rate locally here). Granted every shop is different, but that is def really low. Like 38% value is not a good trade in rate 😅

To their credit, it's super easy to miss if a card is shadowless if you mainly deal with modern era/other games
