IS there really such thing as penny stocks?

i always wanted to be the fortunate one who put $$ in google 10 years ago when it was less than $50/per or netflix when it first started.. you know? (im sure we all think the same way!)

but i’ve heard of someone say the term penny stocks.. but i havent actually SEEN them with my own two eyes so any help is appreciated
thanks 1st replier. i didnt literally mean $50, just $50 as in “cheap” for google.
