I'm curious what type of loupe's most people use to look at their coins. I have a few that I used quite often: 1)RUPER x3, x4, x5  ----------------------------------------------------------- 2) RUPER x10, x20  ----------------------------------------------------------- 3) SUNRISE x30 Light Scope   ----------------------------------------------------------- 4) U.S.A Table type stand loupe   ----------------------------------------------------------- 5)x200 / x800 Digital USB Microscope by Auchans (sorry no pic) Curious to find out what the majority of people use...  |

I mostly use an old 50mm camera lens as a loupe.
For any Miranda (camera) collectors here, it's a Miranda 5cm f/1.9 lens -- non-PAD type. It's pretty cheap compared to most other old camera lenses, and it's not measurably radioactive (i.e. contains no thorium, as far as I can tell).

I use a Japanese 10x cloth examination lens, 3 elements in 2 groups. No distortion or color aberration a huge depth of field. Can be used with the lens 25mm from the coin, with the eye half a metre away,
or with the eye 10mm from the lens, with the lens 25mm from the coin also.
It was originally used in a weaving factory, way back in the 1930's. Black lacqured brass mounting for the lens, a lot of the lacquer has chipped off.
I also have a 20x gem examination lens with an extremely narrow depth of field. The narrow depth of field is for examining flaws inside gemstones. Not of much use for coins, unless looking for variation of details in mintmarks, etc.

To be honest, for what I collect I only have use for a 3x foldaway lens I bought from my opticians and a 5x jewellers' eyeglass my Dad used to use.
Ancients / mediaeval coins are what I collect and if it's not visible by eye it's not too important! The only real use I have for a lens is to check for overstrikes where die has been altered.

Anything my cheap Bausch & Lomb 5/7x duplex isn't up to, goes under my camera lens.  |

A jewellers 10x triplet for most coins, that one has a sentimental value to me as well, since I bought it for taking a gemstones course in my undergraduate degree. Made in Germany, cost me over $200 in the early 1990s.
For closer looks, I do have a fantastic 20x lens, made by Iwamoto, by far the best optics I have ever used...

I've been doing some research the last couple days, and found that there's no real reason why I can't use my imaging setup (tethered Canon dSLR with duplicating lens) in Live View to survey coins onscreen for extended periods of time. My loupe isn't going to get much use into the future. Google "(your camera) sensor overheat" to see where I went. |

Ancients / mediaeval coins are what I collect and if it's not visible by eye it's not too important! The only real use I have for a lens is to check for overstrikes where die has been altered. I tend to buy a (relative) lot of late Roman bronzes and Russian wire money - series both known for relatively small coin size (and the latter are also full of tiny letters). So yeah, I'm accustomed to looking for details a bit too tiny to see with a regular eye... so I just take off the glasses. I'm terribly nearsighted - around minus 8 dioptries - so without glasses, my best viewing distance is somewhere around 2-3 inches, which makes me able to see very tiny features (and yet I still sometimes end up with coins - usually modern ones, naturally - which seem to have details too tiny for even me to see; in which case, yes, I take an old 3x or 5x loupe and try to look through it). |
