Started out punching 88 column cards in 1976. Ended up repairing commercial ware wash machines and now my feet hurt. Never been to a major show but might try Central States next year (my son lives in Chicago).

I'm in the copier industry and every time one breaks down or needs to be installed the treasure hunt begins. If I get lost for a couple hours the boss doesn't complain much at all unless, I just get mad at myself. So I should know a lot about toners. Last weeks hunt had this one thrown in. Can you tell me if this w
ould catch a Cameo? Several pics trying to figure out lighting but the cell pic shows the truest color. Thanks!
Beautiful obverse cameo for sure. Reverse needs to look like that too.
Went off to college in the late '60s to study Math/Physics/Computer Science with the dream of going to work for NASA. However, after four years, the moon shots were just about over and NASA and the Aerospace industry were laying off by the thousands. Hung around in Grad School and picked up a M. S. hoping things would turn around but they didn't so I got a State job as a Programmer writing in Cobol and Fortran IV. Spent the next 30-plus years climbing the corporate ladder in the IT field and finally retired as the CIO of a State Agency. Then, I was able to turn a hobby into the ideal retirement job and, for the past 10 years have worked as a cataloger for a certain auction company based in Texas. Love the job and, as long as they continue to like me, I'll keep writing catalog descriptions until I'm carted away (the job also provides the funds to buy some serious goodies in their auctions).
BS Chemistry. Working in Pesticide, Hydrocarbons, Neutraceutics and now medical equipment/supplies testing. Analytical testing 25+ years. Work with a lot of organic solvents, so I get to "experiment" and see what works, and what can cause unwanted side-effects.
I have worked in the Department of Public Works sector of local government for two small municipalities for the past 33 years. Started off as a maintainer I.15 years ago I was asked to go back to school, received an engineering degree 10 years ago and currently am the Director of Public Works. I have really seen the good the bad and the ugly working in government. Now that I am in a leadership position after working my way up the ladder I am able to make a positive environment for the staff and residents that I work for. Sorry about the poor condition of our roads, bridges and parks. I know most people are down on government officials but where I can see, the effort in my department is very strong and to a man and women we all work hard and feel blessed to be serving the community. As an added bonus there is another staff member who I recently discovered collects world coins.
Enthusiastic collector of British pre-decimal and Canadian decimal circulation coins.
Man Of coins, I have stage 4 Kidney disease and some other wonderful issue, you just might be able to have your degree advance your numismatic interests!
I'm an expert of nothing. Will continue to offer opinion as I see fit. Regard at your own peril.

The original reason I started this thread was that some members have experience with things in their training/professions that can be helpful for other numismatists. Y seem to be a perfect example. Please share your thoughts on any chemicals you have used on coins.

My favorite solvent to remove hazing or PVC is Methylene chloride or chloroform. I have found that Acetone can be a bit reactive- especially with copper - and, unless you can get lab-grade solvents, you may be introducing impurities that could be residue you leave on the surface of the coin.
That is a very good point about the purity of the solvents. 99% pure is good enough for most applications but even small traces of impurities can do nasty things to the fragile surfaces of coins.

I think the reverse is better, but I won't know until it gets shipped back from pcgs.
