Citeer: "Elcuco"What do you think? Corrosion? I think the coin lost his value.
Have a nice weekend day in the north.
For me, the exact opposite effect -,,the coin is thus rarer - more valuable - and more natural,,
Because it describes exactly what it is made of and how long it has been in the world. Silver is mostly supplemented with copper or other metals in various proportions since time immemorial. Therefore, we state purity in proportion to the purity of silver ( 999, 0,750 , 0,200 etc.)
Issuing authority - monarch -began issuing a 0.700 purity coin
and then gradually pushed the mincmistri to save and gradually devalue the coins by adding cheap mixtures ( it was seldom the other way around) rather, it was a war or a new minting of new coins.)
To your coin: certainly in my humble opinion (someone would have to support me ) so for me it has a larger coin value which is legible that it has not been chemically purified , furthermore, the coin was not artificially sprayed with a mixture of dyes to cover unpopular corrosion ( which would still bloom and drum under the spray)
I think you saw it in PM when I showed it with a Roman coin what is under a beautiful brown spray of,, green copper patina,,
You once published a coin here with artificial spraying of a brown mixture on a coin unnaturally the same on the whole surface- I didn't respond because most collectors would be affected and upset (because they like deception and fiction more than the truth)
Look at doing with the metal the influence of moisture and especially time, however, also the storage and influencing of other chemical substances near the coin.
A little long, huh? Definitely more acceptable coins and therefore more expensive. For me, better than brown painted, however, I recommend stopping corrosion by using the recommended oil .
There are a lot of collectors who know by observation and experience what is natural and what is not.
