There are some projects for stamps that are using spectroscopy to solve a few long standing questions. All of them so far have relied on outside funding - grants etc.

They've found some interesting things. Like a certain reddish brown ink that has been assumed to be rust particles in linseed oil somehow includes exactly no iron whatsoever. So much for what's been "known" for over a century!

Old ink formulations were often trade secrets, especially the ones for printing.

The specific info about ink formulations and other stuff would probably apply somehow to older autographs, but probably not baseball.

Most authenticating of stamp stuff is done a lot like autograph authentication, examination by someone experienced with the exact specialty. I've seen one of the experts doing a bit during an antiques roadshow type thing they did at the 2006 international in DC. Stuff I was fairly sure of after a few hours of checking he confirmed in under a minute!
At least I was right..... (One good news, the other not so good but no loss so an inexpensive lesson. )

Currently there isn't much science involved, but that's slowly changing as the science gets more affordable.
I have a stamp out at the PF currently that will be the first of it's kind certified assuming they agree. A variety of one of the 1873 officials that was only discovered and identified fairly recently.
