That all depends on how intricate the PA state ID is.
I know here in CA, fake IDs are hard to make because of the million plus tamper-proofs.
I had a fake CA ID that I paid 500 bucks for! It swiped right, bended right, passed UV and IR light tests... everything!
But then one day when I was pulled over by a cop I accidentally gave him the fake instead of the real. So be careful with that.

Now as a Bartender, I'm going to be real with you:
We really don't care if you have a legit ID or not. All we care about is that you give us SOMETHING that at least looks enough like an ID so that if $hit goes down, we can shrug the blame. There have been a few times when a person has given me an ID and I was able to find one flaw in it pointing to it being fake. I still technically served him because
-it looked enough like a real one
-the guy looked over 21.
As long as you tip us, are nice to us, and don't make a scene we usually don't care.
Now that all depends on the type of establishment you're trying to get into.
Big, poppin clubs will have multiple bouncers specially trained to spot for fake IDs. I'd avoid those kinds of places with a fake ID (especially since many of them will then keep your ID).
Small pubs / bars / little dance halls, you know... local places, usually are less strict.
Before you go out spending money on this, do plenty of research (as I did for mine many years ago):
Find out exactly what a PA ID looks like (I mean REALLY study it. look at every little minor detail).
Read exactly which security features are on a PA ID.
Read to what extent PA is prosecuting (and how severely) fake ID cases
etc.
