Oops, got a little off topic, but one of the reasons I remember this so well is the intricate equipment he had for fixing old watches, which included magnifying devices I'd never seen before in person. Probably early 1900s.
@Randy Abercrombie I use them all the time in my electronics work, but rarely a 10X. Usually about a 4 or 5 X is enough for me. Great for finding solder and board defects. We also have loupes like @VistaCruiser69 posted and sometimes I use those. The lighted ones are great. And we also have some scopes like @Inspector43 posted. But I prefer the loupes.
As far as the Stereo Zoom Scope, I use that when I am cleaning ancients. It's not much good for anything else. I think 5X is about perfect for coins.
How is it that a day does not go by without you nice people making me feel like I live in an antique shop? Sigh, here it comes again, old dude story. Once upon on a time just over four decades ago when I was a young electronics technician, my re-work person gave me an eye loupe because I kept asking to borrow hers. She had an extra but older eye loupe and gave it to me. There was pink finger nail polish on the rims so that everyone knew it was hers and hands off. She was really good at her job and I felt proud to have her hand me down eye loupe. Since I'm really near sighted, I only use it for the micro stuff. The lens pops out on occasion but my old Bausch & Lomb still keeps ticking.
Based on some of the replies here, maybe search out a cool vintage loupe to carry around?! Quality and history all in one!
That may depend on where you are and where you are calling. Where I am I can call SOME numbers that are outside my area code without dialing the 1, but there are also numbers WITHIN my area code that I DO have to dial the 1 to reach. And that is WITH a cell phone.
Holy moly. Going through some of my grandfather's bags of bulk coin, i found an old loupe of his. Things are coming full circle, lol.
My coin dealer gave me this 7X magnifier in 2007. I use it all the time when I go to a coin shop or coin show. I carry it in an empty prescription bottle.
