Hi Justin...I have never puchased a Griffey Jersey, but bid on them constantly with lots of Authentication. Its a relatively easy item to find on Grey Flannel, Heritage, Hunt, Legendary, American Memorabilia etc. keep your eyes open and you will find exactly what you are looking for and I will keep my eyes open and send you the next one that I see. I must admit, you will find quite a wide variety of styles out there as others have suggested.

GOOD LUCK!

Jeff
