brucedoe,

For companies that are "tied" in the number of years, the second and third criteria are earlier Pay Date and (if the same Pay Date), earlier Record Date. I figure since we're talking about the length of the streak, it just makes sense to give the edge to the one that raised earlier...even if it's just a day.

I don't know of any previous 60-year companies, either, but anything's possible going back into the "dark ages" of a few decades ago, when nobody seemed to be keeping track.

Happy to say that I still own 3M through its DRIP...;)
