What would make this perfect circle on a coin?

[DigToChina]

Plucked a coin while detecting on a beach on Saturday. As I was recording my finds today I became curious about what would make a perfect circle on one of them. I swear I've seen this on other coins and I'm betting someone on here knows. Is this from a vending machine or something?

Edit: now that I'm really looking at it, there is a weird "comet" like tail under the 'beth' too.

That coin was encased at one time.

You mean like it used to be an uncirculated set and was cracked open to use for face value?

Most likely a pendant bezel.

Thank you enamel7 and cudamark.

Most likely it was the end coin in a machine wrapped roll and the crimping machine scratched it. I see those all the time at the ends of rolls.

Sorry, but I don't know what scratches you're seeing. It was in a bezel at one time.
