I don't use gloves FWIW. It inhibits manual dexterity. Contrary to some people's belief, touching a proof coin does not change its status or gradeability. I have no idea where that myth came from. I'm just throwing that out because I see variations of that sentiment among newer collectors often.
Cotton gloves are good for all types of coin handling - they are prone to 'slippage', so work over a soft cloth or cotton towel to prevent damage if dropped. https://www.jpscorner.com/products/...2&_sid=6ff97f6ef&_ss=r&variant=15098589216831 Latex finger cots are also an option - they provide a better grip: https://www.jpscorner.com/products/large-finger-cots
Cheapest I've found is buying cotton glove liners from a medical supply in bulk. Can get them for around 10 cents a pair or so if you really work at it but they can get expensive like hobby lobby sells a pair for $4.95 in their coin section and it's basically the same thing a pair of cotton glove liners. They can be found also called "inspection glove liners" or "eczema gloves" ect. I break out the gloves when I'm searching a new BU box of quarters for Ws but otherwise if they were circulated I would just wash my hands before and after. Sucks you have an allergy to the metal.
I was going to say Finger Cots however Juris Klavins beat me to it. Another place to look is nitrile gloves at automotive stores or in the paint section of big box stores.
I had to smile at this. I just returned from Idaho last week where I met a cousin for the first time. He had an ancient 1778 family bible with names and dates, wrapped in a bit of Scottish Kilt. It was in an archivable box. He carefully laid it out and handed me a pair of white cotton gloves to hold and open it with. All very serious. I was having a hard time turning one of the fragile pages so he just licked his finger and turned it for me......
The only gloves that seem available in some stores are the thin food handlers gloves, but should work for CRH. https://www.amazon.com/food-service-gloves/s?k=food+service+gloves
cotton latex glove liners for people with latex allergies or sweaty hands, those were the immediate solution to their problems before nitrile and other materials came on the scene. these can be gotten for around $25 for 144 gloves or 72 pairs, or as they put it "a dozen of 12" LOL a gross is a gross. grainger even sells a knit gloves for like 66 cents a pair. this is more expensive at near $50 for 72 pairs. I go with the cotton glove liners, it's thin, relatively lint free, and keeps the fingerprints of of my precious.
Yep, Rubber gloves been around for like 120 years, specifically latex, invented by Charles Goodyear, after vulcanized rubber. make it harder, then, make it softer.... LOL
