As much as I could fit in my pocket
A weird Question...

All of it. Whoever left it there must be very rich, leaving millions of dollars out on the street.
That would kind of be stealing, though.

The only negative thing is guilt

For me, if I just take a bunch of free money I just feel kinda guilty so I'd take like about a small portion, and then just leave...

I probably wouldn't take any money!
If it is real and mine, then why not grab as much real money as possible? However, my realistic mind tells me this isn't the case. I sense two logical possibilities for 10 million dollars or more in cash just sitting out in the street:
1) It is counterfeit and worthless; why else would someone leave that much money around? Of course, less priority of protecting something with no value.
2) It is REAL money, but this most likely means it came from an armored vehicle that transports money. In this event, it is a federal crime to steal any of that money and all of that cash is traced by serial numbers anyway. When the police (FBI most likely in this scenario), trace the money, I don't want to be the one hiding it somewhere.
The smart answer and the honest answer is to simply notify the police and have them come pick up the money. I didn't miss a chance at becoming rich; it wasn't my money in the first place. If it was something I could have "gotten away with", then oh well; easy come, easy go.

Agreed

Big Brain Time
If you were walking down the street and there was a pile of money, how much would you take?
*Note that there are literally tens of millions in this pile this is just a hypothetical question.
