Kelloggs glass cockerel prices?

Question:i have a kelloggs glass cockerel i was wondering if you had any idea on how much they are worth?

Answers:
I didn't know that Kelloggs produced a glass cockerel. Does it say Kelloggs on it anywhere? I know there were glass cockerels produced in the 70s and 80s which were very colourful but were I think made by the Murano glass factory. these vary in sizes but can make as much as £100 at the right place depending on condition, age and size.
