can anyone here enlighten me if they have 1st hand knowledge of a "laser" ever being seen or used in numismatics in their presence other then for etching???
as an ex-aerospace machinist this term puzzles me here
laser's in manufacturing can etch a surface or burn elements i've never heard of "moving by light & energy" the elements even such moving as referenced is quite envolved (ex c/nc programmer here certified in 83') the one's i'm aware of aren't a hand-held gizmo...it's a very precise laboratory piece of equipment from what i recall too laser technology wasn't cheap then...is it affordable now? the set-up itself was quite involved too that involves alot of power consumption
i bite my tongue or probably should have recalling the 1st person to state such a thing (such person is not held in my respect should i add)
so if anyone here...has in fact...seen a laser used in doctoring or someone who owns one that has applicable use please inform me or pm me...i promise to keep a secret
daniel carr is one who could pop in with his manufacturing knowledge...i'd listen as he's a mechanical engineer type been around many a shop machine tool
surely other machinist or mechanical engineer types are welcome too enlighten me...i've been out of trade since 96'...but was quite involved uptil then
everything in life is but merely on loan to us by our appreciation....lose your appreciation and see
Would burnished large cents also be classified as 'smoothed'? There are MANY of these floating around raw in the market place, especially among the pre-1816 coins.
appears to be a loosly used term, if the coin looks as if "something" may have been done to it, and no one can figure out exactly what... its called smoothed.
regardless of how many posts I have, I don't consider myself an "expert" at anything

It has actually been done quite extensively. Think of the advantage of removing a discrete hairline on a proof coin upping the grade a point or two, or making something obvious become inconspicuous to the human eye. I was talking with a knowledgeable second generation dealer who said something about coins coming back from the grading service with a warning not to send them more lasered coins. Anything that can be done to make significant profits resulting in higher grades, has been tried.

was kinda hoping for some depth in the points i addressed... a true laser for shop use can only etch a surface or burn/cut any element a true laser can't raise a sunken hairline true it could etch a raised die polish line off precise movement becomes an issue though...i'm an artist ok...eye to hand control isn't a weak point of mine... "i would not even attempt any freehand address of any kind on such a minute work area" and i'm confident ok
moving metal...i maybe a retired machinist...but moving metal by a laser...just does not compute..."laser=energy induced into light"...there's physics here of moving by "light and energy" that doesn't add up
i seriously would love "an actual fact based reply...or pm in secret" who with m.e. type of background would care to get technical here whose seen one?<<<<not here-say please whose actually seen one used by a numismatic/doctor? okay so price is way down on laser systems as they can be had for $3-4k (stunned a lil)
it's just a loose tossed non-factual proclamation until someone actually steps up here...i lived a very technical past life (why i despise realone)...lasering in numismatics...just does not compute...when refering to "moving metal"...etching is very clear and practicle
I don't have a problem with a generic term like this. I had a Bust half that graded AU "smoothed". It sold. If the agent of the smoothing hadn't tampered with it, it might have graded BU.

<< <i>I have gotten 'smoothed' on a few large cents lately that left me baffled. >>
Yes, I know what you mean. I think it is a catch all phrase for all the things that Stone mentioned.
ever being seen or used in numismatics in their presence other then for etching???

Smoothened copper cents are polished/rubbed with a thumb in a dry cloth.

<< <i>Smoothened copper cents are polished/rubbed with a thumb in a dry cloth. >>
I call those "cleaned".

<< <i>I am seeing more and more PCGS Genuine coins with this notation. How is this being done? >>
I think the better question is WHY is this being done.
The answer is simple; people think it increases the value when actually it hurts the value.
