Congrats! I'm jealous!

Hi Everyone,

Does anyone know of fan clubs that send you an autograph for joining? eg William Shatner

Thanks for your time.

If you were to sell your autographs, or just like it to be 'worth' as much as it can be, doesn't the 'value' increase once it's been authenticated? I'm new to this so this may be a shallow understanding of the process.
