Value of Mopar 8 3/4 center section with 4.56 gears ?

I've been out of racing for a long time (early 80's) . back then a 4.56 was one of the most wanted gears. What's changed ? Why are 4.56 no longer in demand ?

That's a good question. I'm guessing it's because of the prevalence of stroker motors that may not need such a short gear???
