Eye Loupe magnifier recommendation

[Spilchy]

I am looking for the highest grade, best made eye loupe magnifier with either 5x, 6x or 7x magnification. It is to be a hand held loop that you can put on a lanyard.



It is made for looking at coins.



My boss has a multimillion dollar rare gold coin collection and wants a new loupe. The 5x to 7x is what is used for grading them. He will spare no expense at finding the best loupe made. He has a bunch but always wants more.



I figured a handful of you guys would have recommendations.



Thanks!

I have a AGFA 8x sitting here that I never use. Let me know if you are interested in it.

Spilchy- I`ll be interested to hear what you decide on. I know nothing about this type of loupe but I could sure use one myself.



I wonder if the companies that make photog-centric ones (Rodenstock, Schneider, etc.) make ones like this
