Diet Dr Pepper & Regular flat tops values?

[oldcrowncollector]

I know someone who has what I think is this can but not 100% sure(need to look again) but I know both are flats and Diet is decent the other is beat up. But I remember the one saying recipe for Hot Dr Pepper.It is in a collection with some decent cans Black Label Bock(Red one) and some decent zips.Just wondered in average shape what Diet one is worth Regular flat (Dr Pepper is dumper) 80% of collection is humitity and rusted to point of worthless and had some decent soda flats in collection.
