1943 British Three Pence Error Coin Help

Hi Everyone!
I was recently rummaging through some of my grandfather's old collectibles and happened to stumble upon an interesting find from his younger years- what appears to be a 1943 George VI Brass Three Pence with (what I believe to be) some form of minting error on the edge of the coin. The error is much more notable on the reverse of the coin, but there is definitely some overlap on the obverse. Unfortunately, the darker discoloration of the coin seems to be a giveaway that its seen some circulation/oxidation damage despite the sealed storage container I found it in. I've browsed the net for any notable 1943 George VI errors but the most I could find was a passing mention of lamination errors. Is it worth my time to submit this coin for grading? Thanks for your time and thoughts.
