Total hours on the airframe

[AP AVM]

Is there a way to know if your aircraft's airframe is high time due to high hours on it Vs low time airframe since new. At what number of hours does airframe becomes high time airframe?

I just found out that my 67 C337B AP AVM was at 9000 total flying hours when it was sold back in 1999 with low engine and prop hours. How would it be classified as in terms of total airframe hours on it since new?
