Fair or foul?

I recently went to the store and found 52 cents on the shelf of the CoinStar machine. Is it fair game of foul play to take this change, because it was not in the reject bin?

I would take it. It's no different than finding the same coins on the ground. No one wanted them and left them there. Nice find.

Fair, in my eyes.

Fair game!
I don’t know why people leave coins up there but they're not coming back for them. I found a dollar coin that was almost unrecognizable because it had been in the road or something. I took it to my bank and added $1 to my coin fund. I don’t know why the original owner didn’t do the same? People are very wasteful I guess.
I keep up with all my spending, and keep my coin money separate from all my other money. All the change I find at Coinstar I add to this fund.

Perfectly fine!

its fine, half of my random world coin jar (none part of my numista log) came to me via that route.
