Bought a bulk sale of ~60,000 cards for $300

I was at a local comic convention in my town, held in a high school court yard, and came across one stall that had this pile of boxes in the corner with a sign saying “60k magic cards for $300”. I joked to my brother that we should get it, but quickly we realized what a steal it was. We called up a couple friends to split the cost 4 ways and bought the whole pile. It then took the four of us half a day to go through 3 of the 14 boxes (we were quickly going through card by card, scanning whatever we thought valuable). With the 3 boxes we’ve gone through so far, we’ve made ~$150 with the cards priced $1 or more if we resell them.
