This could be something that you bought for a higher price than what most people would guess based on the item, or it could be something you bought for a normal price that has gained significant value as time has gone on.
What made me think of this question is a LEGO minifigure I got with my “The Hobbit: An Unexpected Journey” disc. It is Bilbo Baggins in a blue coat that was apparently only sold in that movie box only at Target stores. Even considering the exclusivity, I would have guessed maybe $10-20 for such a tiny piece of plastic, but there are sold listings on eBay from $80 to $225. I could possibly even get towards the higher end of that number since I still have everything in the original box in good condition. It’s not worth a ton compared to some other items people may own, but I think most people would not expect nearly that amount.
I have season tickets for the Raiders. I had them in Oakland, and we got 1st priority when they moved to Vegas. I jumped at the opportunity bc I knew by Mark Davis moving the team to a tourist destination that there would be demand from both fan bases at every game. My theory is that the extra demand would allow me to sell most games for profit, and I could go to 1-2 /year fully paid with the profit. So far that’s worked swimmingly well. I paid the PSL off in year 1 with the profit, and now make ~$3-5k / year selling tickets.
The PSL ran me about $4500/seat and I got 2 seats. They are selling at $30k apiece rn. It’s very tempting to sell them for profit, but I enjoy having the ability to go to a few games and making a bit of profit selling the rest.
Yes, I realize I’m a scalper. Yes, I realize I’m part of the reason our home games have so many away fans. Having said that, I really don’t care. Mark Davis made a business decision to move the team out of Oakland where we had die hard fans like myself going every week to instead moving to a tourist trap 10 hours away. In turn, I made a business decision to profit from that move.
