Polaroid Pronto! camera line

Sometime in 1976 I got the word that the in-house packaging guys had come up with some new concepts for the boxes that had been developed after some recent crash-tests. So it was back to the drawing board, the typesetter, darkroom, light table and Cromalin to come up with kindred designs such as the one shown above, and two dummies, shown directly below. Click on images below for enlargements.

I had a Polaroid Pronto from 1978 to 1980. I have some prints that I'm trying to determine the general time period they were taken. There are a series of numbers on the back of each print. Can you tell me what the numbers represent?
Thank you.

I have a Polaroid Pronto with a case, instruction book, and a 5 cube flash, but no film. Do you know how much it may be worth.
Thank you
