Do all PCGS slabs with NFC chip technology have the secure plus shield?
I was interested in a coin on Ebay.
Pics are a little blurry. When I do a cert verification it checks out BUT says NFC technology.
It looks like an older slab.
If I understand the question, No.
I have Shield holders, and holders that look normal (plain) from the front but have the yellow shield and NFC technology logo on the back.
Hopefully that makes sense
