I think you've come very close to a great idea; one you could sell. Develop a clip-on or a sleeve magnifier made to fit coin slabs that could be clipped onto the slab or slipped over the slab you want to view and then easily removed for the next slab. You could sell them on amazon, and if the price is right, I'd buy one in a second.
Not at all. I was told to wear them for two weeks to acclimate. I was comfortable in two days. Not everyone is the same. If you do try them I hope they work for you.
Randy, the Fresnel lens is available in a number of different configurations for consumer use (we won't talk about their use in marine lighthouses). You often see us older folks with less than perfect eyesight using them in book sizes to place flat on their media of choice (newspaper, magazine, book, coin auction catalog) and because the focal length is so shallow, the lens will magnify the text clearly. With slabbed coins where the coin is farther away from the lens due to the plastic housing of the slab, there is a possibility that the distance exceeds the focal length of the lens. The material of the lens is usually plastic and you can buy a dozen credit card-sized units for $5 or $6. So, yes, you can keep one in your wallet, one in your car, one in your bedroom, one in the living room etc. for next to no money. Go to Amazon, type in "Fresnel Lens" and take your pick of hundreds of offerings. It's a very low-risk experiment to see if this would help with your issue. And even if it doesn't work for viewing coins in slabs, you will undoubtedly find other uses for them, even if just to scrape the ice from your windshield in the morning.
Been there, done that, with a Lucite toilet seat filled with clad coins. You get sore arms, lots of Lucite shrapnel -- and coins that were polished before they went in, and polished and bent by the time they came out. Lesson learned: don't buy silver coins in Lucite expecting to get them out, even if they're selling well under melt value. It's not worth it.
I have a lovely proof set from 1958 in one of those Lucite cubes. I believe that is where they will continue to reside until I leave the party.
Not sure of my thoughts on a magnified holder but I tell ya what, I like the ones that have the description on the top of the slab so you can see it while it's in with other coins in a box! The older I get though, the harder it is to see those cents!
There's a big gap. I was thinking acrylic decomposed before melting, but apparently it melts at 160C, well below silver's 962C. Might be able to melt it off with a corn-oil bath. Hmm.
If your college bathrooms were anything like some of ours, it would really drive home the concept of "filthy stinking rich".
My dad bought a new lighted magnifier. Works pretty good. He was telling me he found a penny he's never seen before , i guessed and said it's probable a Bahamas cent. I was right lol
