Question about my double eagles

There's always one. Listen, check the ingredients label on your "100% Pure Acetone" you picked up at your local pharmacy, look up that strange additive in it that goes by the name, "Denatonium Benzoate," and pay particular attention to why it's added in. Better still, I'll save you the time of looking it up...

Denatonium Benzoate
The Bitterest Place On The Web
http://www.denatonium-benzoate.com

WELCOME TO THE BITTEREST PLACE ON THE WEB
Denatonium benzoate is one of the most bitter substances known. Just a few parts per million will make a product so bitter that children and pets will not be able to swallow it. Denatonium benzoate makes sweet but highly toxic products such as antifreeze and detergents taste foul. Research shows that people can detect denatonium benzoate in water at 50 parts per billion. Denatonium benzoate is bitter at 1 to 10 ppm and most products will become undrinkable at 30 to 100 ppm. Denatonium benzoate is also stable and inert. In addition, so little is needed that the properties of the product remain unchanged.

Both the National Safety Council and the American Medical Association recommend adding denatonium benzoate to products that are defined as mild to moderately toxic. Some countries, such as France, have made denatonium benzoate mandatory in antifreeze. Others such as Italy have made denatonium benzoate the number one denaturant for ethanol. The State of Oregon has required that it be added to antifreeze and windshield wiper fluid since 1995. We offer denatonium benzoate in powder form, both technical and pharmaceutical grade, and in a granular form (technical grade only). Your best source for denatonium benzoate is Aversion Technologies, the world's only company dedicated to the supply of products to protect people, plants and pets.

Maybe it's in the acetone you buy at your pharmacy. Not in the reagent grade or painter's grade that I buy. I never buy it at pharmacies.

It's in the "100% Pure Acetone" every one of us buys at our pharmacies, because it's the law. And it's the one we dip our coins in, every day.

 

My experience has been the same as @calcol 's .

Where do you get yours?

 

Thank you for the advice.

 

What law? Maybe a state or local pharmacy board law or reg. Definitely not required outside of pharmacies in Calif. (if there is, it's widely and openly violated). Don't know about pharmacies in Calif. because I don't buy it there. Doubt there is a federal law or reg requiring it in pharmacies. If there is, I'd like to have a ref.

Amazon and Home Depot.

Really? I'll have to see. Can you show us what you get, or what's on Amazon, a picture of it? I of course want to check out the ingredients labeling. Thanks in advance.

 

Go to Amazon and search reagent grade acetone. You'll want one that meets ACS specs (American Chemical Society; see link below). At present, prices are better on eBay if you do the same search. If you think about it, no research chemist or manufacturer will want some foreign substance added to the acetone they are going to use. If you google ACS acetone, you can find lots of vendors.

The URL for SDS for the acetone sold in Home Depot in N. Calif. is below. No bitterant added. I happened to have some handy in my shop, so I just tried a taste. Not bitter at all. Would you like me to send you some?

Yes, I get what you're saying. Likewise I guess you know most of us aren't using that "high octane" (lol) grade you professionals are using.

 

I buy acetone at the paint store. It is used to clean ink from silk screens and oil base paint brushes, as well as other cleaning uses. It is not a pharmacy regulation in my state.

 

Maybe this explains why the can I bought at my local hardware store doesn't list any ingredients other than "pure acetone".

 

Well in this case the no motto is a plus as they produced 156,359. 1908 P's with the motto Compared to 4,271,551. P's without the motto.
If your going to start collecting?
You should at the very least have a couple cheap tools to check for authentication.
A cheap digital scale is a good start and handy to have for other things around the house.
If you could post up a picture of the coin edge also, I'm curious about a seam.

 

Sunnyside acetone, don't remember if I bought it at Home Depot, Walmart, or the local hardware store (most likely the latter -- shop local!). Here's the product data sheet:

100% acetone. No added ingredients whatsoever.

Looks like Walmart now sells Klean-Strip acetone:

100% acetone.

I'd expect nail polish remover to have a bitterant, if only to keep people from gnawing on their nails before everything's dry or gone. Not solvent-grade acetone, though. It apparently tastes foul enough already on its own.

 

Now this is a responsive reply. Thanks. Let the record reflect, I looked it up, I tidied up my point of view, and I now have a New Attitude...
