Holy cow, what an asshole!
The paystub was in an oily envelope on the pile of oily pennies.
I bet this grade A asshole voted for Trump. Both times.

I would spend all weekend separating the copper from the zinc pennies and looking for error coins, rare dates, wheat pennies, high-grade uncirculated specimens, impaired proofs, foreign coins, tokens, etc. Who knows, there might even be an Indian head penny or two in that pile.
You could volunteer…
But even before any valuable coins are found, Andreas Flaten could secretly buy a valuable penny and very publicly get it appraised at, say, $100. He could then honestly say (on camera, of course) “I’ve barely started to look through those pennies. Who knows how many of them are valuable. Thanks, AOK Autoworks!”
eta: Ooh, not just appraised… get the local news to shoot Andreas selling a penny to a local coin shop, and the proprietor says “I’ve never seen such a perfect example of this [1909-S Indian Head Penny with the Indian Smoking A Peace Pipe]! Here’s $450! Now, you need to get back to searching that pile, who knows what else you’ll find!”

The paystub was in an oily envelope on the pile of oily pennies.
I can almost hear it:
“Your honor, here’s a paystub… but we claim there was no check enclosed with it. We are here today requesting a copy of the cancelled paycheck to show my client was paid.”
