Gilded Constantinopolis ?

I really can't comment on the frequency of which this occurs. Without seeing it in hand I can't tell you if that's gold or silver. If its silver its not unheard of, there are some for sale If it is gold, i am almost certain that it was done in the modern era to an authentic ancient coin, if not in this century then the last. I don't recall ever seeing gold gilded ancients besides Axum.

I strongly doubt that even reagent grade acetone would have any effect on the coating or the surface of the coin, especially in the short term. I would not recommend doing this, there is little to be gained by attempting it. I don't think there is need to change the state of the coin. I am a big fan of the as is.

I'm quite sure that the coating is ancient mainly because of the wear pattern on high points. For comparison, another that I once owned, a follis with a "gold looking" silvering (never had any doubt about that one). The main difference being that its surface was mate, not as "glittering" as the Constantinopolis. Not sure if that mean anything :foot-mouth:

 

Dionysos.
this is way awesome, myself i would leave the way it is..i would like to say that at my last coin show i met a guy with great looking coins, they were way out of my league, i was listening to him talk to another person, which i would wish i would have stopped listen longer.
Anyway he was telling this person about man made patina's. Well, the kind that was made when the coin was buried, cloth bag, clothing and dead bodies, skin would put a weird color on the coin..:foot-mouth:,He had a coin with dead skin patina, maybe where ever this coin came from, something may gave it the color its got....just food for thought..

 

Thanks Eng :high5:

 

What color was it? What did it look like?

I would think it would be rather difficult to determine that it had a DB patia, but that wild any way you look at it.

 

Can no one read my above post?

Use an XRF to find out... An XRF is used to find what makes up an object, and can go all the way through.

 

Umm, permit me show my ignorance. What is an XRF? I assume the RF stands for radio frequency?

 

That sound even scarcer than a gilded lrb

 

Bing, this Is one thing most are ignorant about...
XRF means X-Ray Fluorescence

It is used for chemical and/ or elemental analysis.

And Dionysos, most Uni's will have them... Just need permission.

I'd kill for one of these.

As well as a 3D printer.

 

It's a tricorder!

 

Same Anoob...

Both would be great!

 

Thnks for the education windchild. Now I will have to look it up in the net.

 

At my job we have a real nice AA Spectrometer. I could in theory take a small sample (destructive) from the coin dissolve it in an acid, dilute and determine its composition. I have never brought me self to attempt it.

 

Forgot to add,

It's non-destructive.
