T206 Polar Bears are a fun back set to collect. With 250 subjects in the subset, there are plenty of HOFers, but none of those pesky Southern Leaguers. They are common enough to make completing the run within reach, but uncommon enough to make it a bit challenging. Of course picking up Demmitt and O'Hara will cost a bit, but there are usually a couple available for purchase at any given time. The only negative is that Polar Bears are very difficult to find in higher grades (6+). It took me about 1.5 years to collect the Polar Bear set in 2008-9. Average grade was probably G and most are F-VG. Total cost was about $13,000. Yes, I still have all of them. And no, I'm not interested in selling or trading any of them.
(After completing the Polar Bears, I moved on and completed the pesky 48 Old Mill Southern Leagues subset

Best Regards and Happy Collecting
