Microscope for Detecting Forgeries


In a previous posting, Igor mentions using a 100x microscope to detect digital forgeries.

I have often thought of using a microscope to examine overprints for forgeries. For example, comparing overprint inks and whether an overprint in over or under a postmark.

I also thought it would be useful in studying rasters on Soviet stamps.

But what kind? I figure a binocular microscope with an external light source. Also several magnifications up to 100x.

But they seem to range from junk to super-expensive.

Any ideas or experiences in buying a using a microscope to examine stamps?

To study screens (rasters) you need 30x microscope. Really you even can use 10x magnifier.

I use 100x microscope to identify digital forgeries.

There are some microscopes at eBay. I have bought one and found that quality is not so good because you see small black dots all around. May be it is good idea to buy microsscope at some store. Just keep in mind it should be portable with light.

Use link below to see how it looks like.

Dear Michael,

The Samovar was too complex for my near 80 year old
brain so Gary in past has converted my emails to him
(for the Samovar) and set them up. Not surprising,
with all thats going on, he has passed the buck back
to me. So I have learnt how to visit Samaovar and add
my comments, (even though some are 4 years too late.),
using Y2Y but having seen your reply to me, to which
the answer is probably yes, I dont yet know how to
answer your reply on the Samovar. There does not seem
to be a "reply" button.

Just over a year ago we downsized to a town house with
a nice small enclosed garden which I have paved, etc.
to get rid of grass mowing, etc. There is still a lot
of work to do but I am back in action as far as
Russian stamp forgeries are concerned. I have quite a
few questions for you relating to your entries on the
Samovar but enough for now, its getting late. Regards Ray

Dr. Ceresa sent me email about microscope he has:

"Igor, My Christmas present to myself, from a local supermarket of all places, was a BioLux Al 20x to 1280 x Bresser German Microscope, complete in a great wooden case with countless attachments for less than $200.00. If you are a PC man its great as it has a PC occular with CD so you can view on PC, enlarge further, print, copy etc. I have not yet been able to use this feature myself as I have a Mac computer and have to find and buy a 'conversion to Mac from PC' which works on my Mac G4 system. I have seen it woking on a friends PC and it is fantastic, just what philatelists have been waiting for. Ray
