On a side note one of my players had the audacity to ask why the black ncv chip is worth so much and still not labeled as $100. At the time I agreed and was upset, which was why I got gear labels to temporarly fix it.
That got me thinking. To relabel them as 100 would cost me $1.1k for the chips and $200~300 to remove the inlay, so probably could have got $100 primary at a premium to start instead of going thru the hassle of overlabeling or relabeling. Not sure if theyre available in 600 quantities tho.
Anyway good luck with your search!
