While taking apart the bowling machine this weekend we found stuff. I almost thought it was a kid who was stashing treasure:. A poker chip, with silver  colored insert, in a plastic envelope;. a card of dice, one pair missing,  a gun barrel cleaner; shells (1 or 3 each) form a  .357 and a .22, several ( half dozen) bayonets, and i mean bayonets, switchblades ( illegal now in MI) and daggers;  an NOS pocket calculator ( from the size, early 1980's) a   mint CB radio and antenna( 23 channel) . There were also   several of those coin books, filled or partially filled with pre war pennies, on I think was Buffalo nickels, quarters, etc.
The worker form the estate sale  promptly grabbed the stuff as it was coming out. I don't know if it will go back to the family, or not.  
I didn't want to raise a big fuss, after getting what i thought was a steal  on the bowler, and  it was evident  the machine had to be taken apart to  put the stuff into it, something that wasn't done before I got there. And I didn't get a good enough  at the coins to say, I could have  bought an RC81 or Victor cooler  with them, and while we were still  on the property , the item was already purchased in full. 
Shrug, next time the topic of " What have  you found in an old machines", I think I will have everyone beat, not many CB radios and  Liberty half dollars in a  CS72 

LOL @ Tim. No body, but hmmm, now that I think about all the daggers and knives..
