I thought it was fairly well known that when listing any HQ items, you list the items as follows:

Nifty Helm NQ 10,000
Nifty Helm +1 50,001
Nifty Helm +2 50,002
Nifty Helm +3 50,003

etc

I do agree it should be fixed, but in the meantime, people who seek out an HQ will know at a glance not only that your item is an HQ, but what level HQ it is.
