The blue chip guys are always safe bets over the interim to long term. The beater "A" Goudey Ruth went for $4,200, the 2 Goudey $9600, the 2 Goudey premium $3,900, Kashin 6.5 $9,000, even the A W515 went for $2160. I have to think that any nice looking 3-4-5 1920s Ruth is a $5,000 card now and I would not be surprised to see the nicer ones routinely selling in five figures in the next few years.
Thread needs a Ruth card...
