A person leaves a nickel on their balcony...

Here's their report and a question:

TLDR: I left a nickel on my balcony near my birdfeeders and now there's a hole.

I could be totally overthinking this. I have a small balcony facing a small wood. I have a few birdefeeders and I get all kinds of birds everyday. Basically, is it possible one of them pecked this perfect circle into my nickel?

I left it out there one day after seeing my first crow. That was a couple weeks ago and it didn't move at all til just a few days ago. I thought it may have been frozen to the deck. Eventually it had been moved and I noticed this hole! The back side seems to have the metal still present and folded over, I thought that might help confirm what had happened here. Anyone know how easily a bird could do this? Thanks!

The explanation was one that most readers of TYWKIWDBI could have predicted:

"A bird would not do that but it’s possible it took your nickel away and brought back another that it found.  I would continue to experiment."

Other replies:

"My crows brought me a bullet casing and a child’s Jack among other things they love shiny!"

"I had a murder of crows I left roasted peanuts (unsalted) and nickels out for. The nickels disappeared and one time, there was a very shiny dime and a silver gum wrapper in the spot where I fed them! Prized possessions."

"The Xmas tree fell a few years ago, and the string of beads broke.  Wife had the brilliant idea to put them and peanuts in a flower pot hung from a tree limb.  The crows rolled in.  I get gifts almost daily. Glasses, coins, beads, metal shot glasses, a car key to a jeep wrangler, dog tags, a medical alert bracelet, silver crosses, necklaces.  They hang out to see my reaction.  They harass the crap out of the local hawks, who think they want one of our chickens.  And, I might give them leftover hotdogs when I'm grilling."

I have heard of this, but never experienced it.  Our crows are gone for the winter, but I think this summer I'll leave out some shiny new nickels and see if they will exchange it for an old buffalo nickel or shield nickel.  Any reader experiences in this regard?
