I found this amusing I guess because I have the same issues. I'm old enough to find much in my life amusing since my father told me I would have to endure all these things as I age.
the last coin show i was at....that was exactly my problem. poor lighting, coin in a flip with staples, couldn't get it the right distance from my eye to see it very clearnly..and didn't quite grasp how much all of the above factors were messing with my perception. brought home this coin for 11 bucks... this is a fantasy piece from about 10 years ago. didn't know they made these, but it should have been plain as day that is wasn't a coin from the early 19th century. when i got home, it was plain as day. i would have paid 1 buck for it. so i guess got a 10 buck lesson on how bad my vision is.
After the coin show today: The reading glasses were the best answer I've found so far since they retained the 3D view with both eyes. There is a lot of difference in quality od such glasses but I was happy with the $1 pair I found (after trying on several others which had less quality control).
Good to know. I will bring a small LED light to my first coin show. "Old age is when everything hurts. What doesn't hurt doesn't work."-- a framed needlepoint my grandmother made. As a child I thought it was strange and frightening. Now that I'm older it makes me laugh, nod, and sigh.
I found a pair of reading glasses I had back when I could still wear contact lenses. As you say, it looks ridiculous, but wow - I did not know what I was missing! The magnification marking has worn away on these, but I think they are only 2.0 or 2.5 - I'll look for some stronger ones. Thanks again!
