Chipped tank??

[IHaveAquariums]

So ive noticed this on my 29 gallon that I got for my birthday from Goodwill I believe. (Side note my Goodwill recently had a 125g with 8 t5s and some undergravel filters for $55 ?) anyways is this something to be worried about? Thanks!

I'd be concerned it may leak as the chip looks to be all the way to the silicone seal ,
