Those with a premium should not need more than 9x. Plenty DD's beyond that but greater magnification IMO puts them in the flyspeck category; no real premium but intellectually interesting.

John1 Moderator United States 56855 Posts	Posted 05/22/2017 05:26 am Start with a 10x doublet. If that isn't enough for you go to a 12x doublet. I use a 14x doublet and sometimes a 14x Hasting triplet.You should never need more than 14x as a jeweler's loupe, only in a scope would you need more. John1 Report this Post to the Staff
CoinMasters Pillar of the Community United States 5964 Posts	Posted 05/22/2017 11:16 pm I use a 10x loupe to scan coins, and when I find something interesting I switch to 16x for closer examination. Just use what suits you best, keeping in mind you may want to have a decent look at something small like a mintmark. It's good you're enjoying it, if you want to hurry up that "matter of time", look at a lot of coins. I buy rolls at the bank. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 05/23/2017 12:46 pm 10X is the considered the desired view of a doubled die. My scope goes to 35X and sometimes when I take images at 35X, the camera won't pick up the minor ones I see. So a variety that you need over 10X would be too minor to command a premium. I see a lot of images is single devices that some will view at 60-100X. That is a waste of time. Even nothing looks like something with that much zoom. Report this Post to the Staff
CaddoFarms Valued Member United States 61 Posts	Posted 05/23/2017 8:34 pm I pick up circulated change everyday. Probably a dollar or more, daily. I suppose I'll need to look at EVERYTHING that I come across. I did see a "good" War Nickel last week. Should've gotten it. Report this Post to the Staff
Conder101 Bedrock of the Community United States 17884 Posts	Posted 05/24/2017 11:05 am It depends on the doubled die. Some are easily visible with the naked eye, while other take some fairly high magnification (and some imagination.)to see. Report this Post to the Staff
