We had an Apple II+, IIe and //c. I would inherit each one when my family upgraded. They were around $1300 each I think. The //c might have been more because it was “portable” (you could put it in a suitcase with a 10-pound battery and a weird tiny horizontal screen that wouldn’t work with most software).
My grandparents had a C-64 which they never used. It basically became mine. I think it was $600.
