A clashed die is when the two dies used to make coins strike down without a coin between them, causing a the dies to leave an impression on each other, and an impression of that on the next coins
I can't tell from the photos whether your coin is one or not but Flying Eagle Cents exist where the dies were clashed with other denominations (e.g. FEC obverse clashed with Seated Liberty Half Dollar reverse). The clashes occurred when someone was making mules (coins made from dies that were not intended to be used together) during the middle of the night. In that era (when coin collecting was in its infancy) there were lots of shenanigans going on in the Mint.
