I noticed earlier this year Beckett authenticated two autographs that werent even close to being authentic, both cuts with tape over them mounted to 3x5s of 1919 Reds Jake Daubert and Sherry Magee. Just be cautions as the Bill Rariden for sell on ebay right now I would also say is not authentic. I have never seen him sign his name "Bill" either "William" or Wm". But this is my opinion, which I would say given the time and effort Ive spent looking at 1919 World series autographs is very very good.
