Anthony, the Muffin/Gem pans are a real learning curve! The No. 11 French Roll Pan (P/N 950 has at least 11 variations... I think a few more have been identified since the Yellow Book was published in 1997) :) Clear pictures showing all marking on top and bottom are critical to identifying each pan, for sure! I suspect your pan is a variation 5 , but it could be the variation 4. Either way, these are fairly common pans with values from $30-$50 by today's standards. (I usually cut the Yellow Book values in half). These values are predicated upon a fully restored pan being in Excellent Condition. :) :)
