Fundberichte und Reinigungsberichte zu ungereinigten antiken Münzen
Ergänzende Angaben zu Fundbericht VI, auf Nachfrage zu Korrosion bei Münzen hin:
I would say that the amount of corrosion on these coins is on the high end of what I've seen in recent months and considerably more than on the coins when I first started ordering from you. All-in-all, a very nice lot of uncleaned coins. The Helena AE4 (coin5) and the Constantius II AE4 (Coin1), because of its excellent condition, were the highlights for me.
In the recent months I've purchased (won through bidding, not sofort kaufen) several large lots of uncleaned coins from various sellers on ebay. I puchased lots where good detail was visible in the pictures. Prices varied from 0,50 to 1,75 Euro per coin. In all of these lots the cores of the coins were heavily corroded and covered with a very thin patina. With a coin in this condition the following happens when cleaning: After a soak in distilled water and a light brushing with a soft toothbrush, the patina is gone as-well-as any details (the patina is very thin and underlying coin turns to powder). A coin that shows very good details before cleaning is immediately reduced to a flat slug. In one puchased lot of 55 coins, only 4 were good enough for my collection. None of the coins I recieved from you were so badly corroded to the core. As best as I can tell, on the coins from you that had corrosion, it was limited to surface corrosion. I obviously don't intentially remove the patina to check the condition of the coin itself :) The one exception was Coin10 which I find very interesting because of the exposed layers and that the outer patina is very thick and stable (hard).
By the way, I'm still working on a very nice silvered large Follis of Maximianus I received several months ago in a lot from you. The coin was covered in a very thick, hard crud with hardly no visible details. I've invested at least 30 hours cleaning it so far and I'm nearly finished. The coin has a very fine reverse and fine obverse and full silvering. It's really rewarding to turn such an ugly piece of crud into a beautiful coin.
