Engine VIN number stamping’s can you show me examples?

Hello, hoping people can post me examples of their block serial number stampings in order to help me determine if a car I’m looking at is legit. It Looks slightly ‘off’ to me so far.
I’m looking at 1971 car
Especially ones built at Hamtramck
Thanks in advance!
Why don't you post the ones from the vehicle that you're looking at? That makes more sense.
