This is not the Betty Crocker stuff from 1946. It is much older, Queen Bess Hollow ware from 1924. That's the good news. Bad news is that Replacements has it brand-new (AND SHINY) for $89.95, Replacements #PCABS7. There are some 25% off items for sale too, $67.00. That is your competition. (scroll down a bit farther).
As I've said elsewhere you need to polish it. I wouldn't even look at yours at a yard sale. No offense, just stating my opinion.
