Hi Brian,
if you use sudo for the python scripts executions, you should use sudo also for the pip3 line. So, there are 2 ways for you that should work:
1. Using sudo both for the pip3 command and Python execution:
sudo pip3 install pi-rc522
sudo python3 rfid-dump.py

OR

2.Not use sudo for both commands:
pip3 install pi-rc522
python3 rfid-dump.py

I hope this helps you to fix the error

sudo python3 rfid-dump.py
Traceback (most recent call last):
File "/home/mark/pi-rfid/rfid-dump.py", line 27, in

But the library shows installed:

pip3 install pi-rc522
