(commented on November 20th, 2020 @ 11:06 am)I don't think it was a cruel thing to do to give away your last $5 MPC.
Unless my memory is failing me, in 1965 we did not have MPC.
We used the Vietnamese Piaster.
I just looked up images of the Piaster to include in this comment & noticed it is spelled "Piastre" on the bills themselves.
You learn something new day.
Or should that be every 55 years?
Oops, it looks like I can't attach pictures to comments.
Take my word for it.
