✅ SOLVED I need some help with this embossed brick

[Vermont treasure hunter]

I found this old brick in a dump and I can’t find anything on it. On it, it has the letter P C P C. They are pretty faint so I hope you can see them in the photos. The brick look pretty old and anything you can tell me about it, like age or where it’s from, would be greatly appreciated.

Thank you! any idea of how old the brick might be? Can’t find a date range for the company.

It's not a company, but rather a type of concrete.

It's not a company, but rather a type of concrete.

And only 14 yrs or so old.
