Lock grade system?
On another topic there was a question that brought something to mind. We don't really have a grade system for locks. Here are some ideas:

UNK - Uninstalled, new in box with all hardware for that lock and instructions in box.
EXK - Excellent - New condition but no box or instructions. Has OEM key/code paper.
EFK – Extremely Fine – Near new condition but some wear, all lines are good. May have OEM key or after market key or code.
VFK – Very Fine – Some wear but all words and lines are good. Has working key or code.
FNK – Fine – The lock has been used, all words are legible, Has working key.
VGK – Very Good – The lock has wear that makes some lines not as clear. Has working key or code.
GDK – Good – The lock is worn but works and some things can’t be made out in the wording. Has working key or code.
AGK – About Good – The lock has heavy wear. Most words are not clear or gone. Has key or code but may not work well.
EF – Extremely Fine – Near new condition but some wear, all lines are good. No key/code.
VF – Very Fine – Some wear but all words and lines are good. No key/code.
FN – Fine – The lock has been used, all words are legible, No key/code.
VG – Very Good – The lock has wear that makes some lines not as clear. No key/code.
GD – Good – The lock is worn but works and some things can’t be made out in the wording. No key/code.
AG – About Good – The lock has heavy wear. Most words are not clear or gone. No key/code.

If coin collectors can have a system to grade coins why not us? Again this just an idea so I would love to hear your thoughts.
