If you pick up $10,000 will you keep or return?

10k is quite a bit of money - enough to possibly get you into trouble if you try depositing it. (Assuming you have not regularly been doing cash deposits of such amount). So you have no choice but to report to the police and pray that no one comes to claim it so you can keep it in the end. But then again, if the notes have serial numbers all jumbled up and it's small enough change, I guess you can use it surreptitiously as petty cash. You can wait a month or 2 first to see if anyone appears on paper claiming to have lost this money that is needed for some operation blah blah - in this case, I will quickly return the poor soul the money. But hey, why are we talking about 10K? I would rather be in a position where 10k is like $1 to me. :P

if iam in need of the money then i would keep it ....else i wud return to the owner

i would prefer to back it again to the owner
