This is one coin out of zinc, German Third Reich military coinage, there is an oxidation on the rims, but the coin still looks good to me. It is...
And what about coins made of different materials (aluminium, stainless steel, zinc etc.) Is the mentioned procedure (distilled water then acetone)...
I agree. As said before, my skills with photo taking are quite bad and I will try to improve that. Since it is hard to see any real change if the...
Thanks, will try to form lots or the same countries at least and put them for sale.
Low value coins, some of them might be silver, but no gold coins at all.
So, this is the first result. I am really bad at taking photos as you can see, but next time it will be better. All of the three coins were dipped...
https://www.cointalk.com/threads/proper-acetone-procedure.193708/ The second post describes the procedure. I will share the results.
Thanks. Any idea how long should the coins stay in distilled water/acetone? Also, should I try this on zink, copper, aluminium coins as well?
Should I then bath the coins in distilled water first, and go for acetone? This way, I should be able to clean (hopefully) both dirt and any glue,...
Hello, I found a great post from Doug on using acetone to clean coins. Right now, I have 3 silver coins which are already 12 hours in acetone,...
The main problem is that there will be a large number of coins to be possible swapped (probably 500-700 coins) so I guess selling them on Ebay or...
Hello, I am going through the coin collection which was left to me and there are a lot of duplicates. I put all of them on edited, so I have...
That may be true, but being able to tell what would be properly graded and what will go under "environmental damage" especially when it is about...
According to the PCGS and NGC this would be an environmental damage and the coins would not be graded at all. Which basically means they should...
Thanks. I was more interested in grading than cleaning the coins. In other words, it is still hard to determine which zinc, aluminium or bronze...
Hello, since I am currently interested in the Third Reich era in Europe (quite dark period of time with interesting coins nevertheless), I come...
One more question, since I will have a lot of coins from different countries... Is there any way to see what is missing, to be more precise, what...
Thank you. The first step is to see what is all there and to put everything in database. I found Numista website, which has nice catalog of all...
Thank you all, I got really useful answers and I appreciate them very much. Some of the coins in the collection were stored in plastic flips (in...
I will try to get some photos, if I remember well, mostly of them are 1, 2 and 5 Reichmarks from 1934-1943, some of them with Potsdam Church and...
