Any Experts out there on toning / rainbow Morgans? see pics

Show me any modern professional publication or even article that uses the word "sheen" in conjunction with coins. I triple dog dare you. And no eBay descriptions alowed.

I am sure he is cleaning coins, but I have to sorta agree with him.

I don't know why everything is coming out "bold" in this post...Sorry.

Thanks Jim,
The link you have posted is one of the best descriptions I have read. Nevertheless, I'll add three things that will make it better...IMHO of course.

Definition

Mint Luster on a coin's surface is the sheen or reflective qualities that are produced during the minting process. When a coin is struck, metal flows from the center of the coin towards the outer edge. [This movement of metal over the die face causes microscopic grooves to be worn INTO THE DIE SURFACE that get larger with use.] This process [eventually] produces microscopic striations (very tiny parallel grooves) [on the struck coin as planchet metal flows into the groves in the die] that reflect light back to the viewer in a unique crossing pattern.

Affect from Coin Cleaning

Coins that have been improperly cleaned will exhibit a muted or subdued luster. Uncirculated coins that still have their original surfaces will exhibit a flashy and bright mint luster [possibly subdued when darkly toned] that will dance across the coin as it is rotated and tilted.

As for the word "sheen" and its correct usage, until I looked the word up in the dictionary and called a professional TPGS grader, it looks like the usage in the link, my usage for forty + years, and most of the usage I have heard and read over the decades has been incorrect. I have used/heard "sheen" used in combination with "satin," "frosty," etc. to describe the surface of certain coins. Apparently, it is only properly used to describe the luster (reflection of light from a surface, Doug ) from cleaning or polishing. Nevertheless, I'm too old to stop using "sheen" improperly.

N-O spells no.

You got me.

In the second book I picked up (a coin grading guide) to Self EDIT you, James Halperin writes: "3. Luster - This encompases the brilliance, cartwheel, SHEEN and contrast..."

So I concede, this professionally authored book by one of the all-time leading coin graders was written in 1986! It is not modern.

BTW, you posted some very good advice in this thread. I gave it a "like":

You don't miss a thing do you?

 

You didn't want opinions on the originality of the toning, you simply want others to agree with your biased assessment that the coin is NT. Even in this post, you make the allusion that anyone who thinks your coin is AT is an amateur who simply doesn't understand.

Well I'm telling you that the toning on that coin is not market acceptable and if you submit it to either NGC or PCGS, it will most certainly be deemed AT or QT. Furthermore, the coin is easy to photograph, you just don't have the skills to do it. You are a numismatic neophyte who is throwing a temper tantrum because the experienced members of this forum refuse to tell you what you want to hear.
