Magnifier Study Report

I am going to report on some of the different magnifiers that I have purchased over the past few months.
The first one I will discuss is the linen tester. I purchased it in both ½ and 1 inch square area. When you look thru the opening, you will see the measurement marks along the borders of the square – this is very useful in determining centering.
1. Selsi 8X linen tester with an optically ground and polished 1/2" x 1/2" lens. Black lacquered aluminum alloy frame. Unit folds up and fits in its own vinyl pouch. Measurements are in 1/32 of an inch and 1/8 of an inch. $11.
2. Selsi 8X black plastic frame linen tester with a 3/4" x 3/4" lens. Gives measurements in 1/16 of an inch and millimeters. 5$.
3. Selsi 6X black finish aluminum alloy linen tester, with a 1" x 1" lens opening, for clear and sharp definition. Frame folds flat for carrying in pocket and comes with a protective vinyl-carrying pouch with a Velcro latch. Measurements are in 1/8 of an inch and millimeters. $11.
Considering the fact that the unit is collapsible, it can be used both as a hand held magnifier and when fully opened, it can be laid on a 'protected' card and is extremely accurate in measuring/comparing borders for determining centering. I found the larger 1" size to be easier to work with in general.
Please PM me with any questions - the items I will be discussing can be purchased from a bunch of sources - I purchased these from Jake's Coins.
