Hello

I found this lovely 2 oyster shells with little pearl, was wondering if they are worth anything to sell.
My location is Scotland, thanks a lot for help

I believe what you have found is a damaged shell that was in the process of forming a blister pearl. However, at some point it looks to have been damaged and died, allowing for an internal barnacle growth. The problem with that is that it did not allow the oyster shell to form a shiny mantle layer which forms the pearl's shell.

So if I were to hazard a guess, I'd say this find is unfortunately not worth anything.
