You HAVE to be kidding.....

All cleaning and micro-organisms aside, For all of you buffalo nickel variety collectors, I think the '18 he has is a 2 feather variety. It might be a 2 1/2 feather as I can see a little chip where the third feather should be........................... John

Silver disrupts the membrane of certain bacteria causing it to erupt and the bacteria die. Our new urinary catheters contain a small amount of silver to help prevent urinary tract infections. I'm not sure how effective they are because I haven't seen a patient have a urinary infection secondary to a catheter in years. I never actually looked, but there is a skin repair cream with a brand name of "Silvadene", and it is best I've seen. I've read silver is being looked at very closely with many thinking silver has a big future in the medical area. I also read once there was a period in the first part of the 20th century where new coins were very popular as gifts and were referred to as "shiny coins". I think this gentleman is an ancestor of a "shiny coin" lover.

 

Bottom line:
The seller is an idiot.

 

I don't think he is an idiot at all. He appears to have himself a niche and is going for it. He is providing a product and service that apparently some people want. That is the American way. Who knows he may even start getting them slabbed in the "genuine" category. There may even be a spot in his future to sell on TV.

 

One of the biggest reasons that bacteria doesn't colonize stainless steel and other metal implants (including amalgam dental fillings) is the degree of smoothness. They are polished to a point that bacteria simply can't adhere to them. I know that the metal itself has a natural antibacterial affect to a certain degree, but smoothness is truly the key. That's why when placing an amalgam filling the dentist will polish for so long. That way the filling itself is as smooth as possible and is perfectly inline with prep margin to ensure bacteria has the minimum ability to adhere to the repaired surface.

 

I agree with those saying that at least he is honest, he isnt trying to rip people off...he clearly states he cleans the coin and likes it like that...some people do...I dont mind a cleaned coin if it isnt harsh...not only that but he offers a return policy if you change your mind...

 

the surface isn't that smooth to a bacteria. Streptococci is 0.6-1.0 micrometer in diameter, which is why you need a 0.2 micron filter for a sterile hood. And those hoods you carry strep on them, right on the stainless steel surface.

The reason isn't smoothness, but galvanometric properties that inhibit cell mitosis. It also helps that the hydralanases and LTA's and M protients have nothing to work on.

I'm not going to argue about this Ruben...I know what we are taught in my doctoral program. Plus, this isn't what this topic is about. Lets get back to the coins or drop it.

 

After reading all these posts about bacteria I just completed sanitizing all my coins.
Furthermore, I will not purchase any coins that have not been sanitized by the seller.
All I need now are sterile cotton gloves to touch any of my coins. If the guy selling these coins is looking at this thread he is probably laughing at all of us to include me right now.

 

Wow....

For the record, I have two - the Doctoral in Pharmacy and a doctoral in Pharmaceutics.

Your a Dentist. I worked for a Dental School also, at NYU Kreiser Dental School.

Ruben

 

There's a pretty good chance I will have two before I finished as well. I'll be a Doctor of Dental Medicine (DMD) for sure and there's a pretty good chance I will also be a Doctor of Medicine (MD).

 

Different field. Good luck with the MD. If you want to do that and have a school to take you you in then should go for it, although dentistry might be a better career.

Anyway, neither MD's nor dentists have the pharmacology background a PharmD does

all of which and two bucks gets you a ride on the subway...

Ruben

 

Wow! I can't believe the response to this. I just hope this guy doesn't ruin any higher-grade coins.

One more non-coin-related comment. Have you ever heard of the "Blue Man"? This guy drinks a cure-all called colloidal silver, and he turned blue! See the video: http://www.youtube.com/watch?v=Sa2OpNTX9Ck

 

this is all your fault...

ah - the ole two feather variety Indian Head Nickel.

Never heard of it

The oligodynamic effect (Greek oligos = few, dynamis = force) was discovered in 1893 by the Swiss Karl Wilhelm von Nägeli as a toxic effect of metal-ions on living cells, algae, molds, spores, fungus, virus, prokaryotic and eukaryotic microorganisms, even in relatively low concentrations. This antimicrobial effect is shown by ions of: mercury, silver, copper, iron, lead, zinc, bismuth, gold, aluminium and other metals.

Especially heavy metals show this effect. The exact mechanism of action is still unknown. Data from silver suggest that these ions denature proteins (enzymes) of the target cell or organism by binding to reactive groups resulting in their precipitation and inactivation. Silver inactivates enzymes by reacting with the sulfhydryl groups to form silver sulfides. Silver also reacts with the amino-, carboxyl-, phosphate-, and imidazole-groups and diminish the activities of lactate dehydrogenase and glutathione peroxidase. Bacteria (Gram-positive and Gram-negative) are in general affected by the oligodynamic effect, but they can develop a heavy-metal resistance, or in the case of silver a silver-resistance. Viruses in general are not very sensitive. The toxic effect is fully developed often only after a long time (many hours).
