Personally, I put a premium on Blanke Wenneker, Nadja-backed E104s and I know many other collectors do too, but I don't know exactly how much. I guess about a 25% -30% premium on a HOF'er and a 200%-300% premium on commons could be close. The HOF'ers are so expensive to start with I just don't think their value goes way up. That being said each HOF'er might have it's own valuation escalator. I think a Mack or a Plank might be a little more while Clarke et al... fits into the 25% escalation estimate. Just educated guesses on my part. And I still need a type 3 w/Nadja back, in decent gd - gd+ condition. (if I am begging might as well beg for what I really want)
