Thread: I like Cleaned Coins and you should to thread

This is kinda like saying the only way to properly clean a stained carpet is by vacuuming it. I suppose removal of the debris on the carpet is a given, but it's the stain part of the analogy that people tend to refer to.

Should I be using acetone instead of alcohol on circulated finds instead of alcohol and then distilled water?

you dont want to use anything after acetone. You just use the acetone.

Although doing a 2nd or even third quick rinse of acetone is usually recommended rather then one single bath.

Urk. That reminds me of two commemorative half-dollars I have.



They've got lovely abrasions on them from some Very Smart Person probably scrubbing at them with silver polish a long time ago. Not me, I got them like this from my great-uncle, who I'm sure also knew better.

I'm not following your analogy. Vacuuming a carpet beats and drags bits out of it, and will eventually wear the carpet out, although that's considered part of the normal life-cycle of carpet. Cleaning the carpet removes stuff that's stuck to the fibers (analogous to acetone-dipping a coin), as well as stuff that the fibers have absorbed (no good analogy in coins).

Coins can be "stained" by things that chemically react with the metal, and by things that just stick to it. Acetone will frequently remove the latter, but generally won't do anything about the former.

The "stain" in my analogy was representative of toning.

When people say that a coin has been "cleaned", they are typically not referring to previous removal of foreign debris from the surface. They are referring to something that was done to improve the appearance of the coin surface (lightening or removal of tarnish). When I ask about proper cleaning, I'm not referring to removal of dirt.

Does the L.I have a clip on the reverse at about 11:00
or is it a reflection?

I was going to say they look more 'well worn' (and it appears that they have seen a bit of circulation) but after viewing those close ups......oh dear. Lots of folks used to clean their coins back in those days. My father took some Tarnex to an old Oregon Trail.

The tip off with those is the shiny devices and dark
protected areas. Someone used a tooth brush on those.

Look at the dark protected areas on this pocket piece I carry. This coin has nary seen a cleaning........

And a dark field and device. Nothing appears odd or out of
order.

Nothing odd? Nothing odd about a guy that would put one of these beautiful coins in circulation?

Artistic after being cleaned.

Are you the one from the RCC who left ASE's for tips inrestaurants?

I might be odd, but I ain't that odd......

I had a bad picture before of this coin roll find. I am wondering though if that spec of something is something I could get of it?
