Ruff estimate-67-and 68

Talked to a woman today that has a 67 barracuda convertable, and her sons 68 notch back. The vert has been sitting since 76 the notch 1990.
Both car are rusted beyond repair and would be parts cars. Titles for both,
What would be a good price for the pair, Im thinking a grand would be fair dont no if she will take it or not.
