Do not touch

Hi,

One who finds an item which seems to have been placed there intentionally - such as a stack of coins - may not move it. If one is not certain, he should err on the side of caution and not touch it.

One who does remove it from the site, must then find the owner and return the item; he may not simply return it to the site, as the owner may have returned in the interim and seen that it was gone.

(Code of Jewish Law Choshen Mishpat 260:9)

Have a great day,
Mordechai
