Hordfest Valued Member United States 208 Posts	Posted 04/23/2023 12:58 pm Quote: I prefer isopropanol (100%) and xylene for copper. That's odd considering you personally advised me to do an Acetone rinse on my copper 1950s proof coins before securing them in AirTites. Do you use Acetone for copper proofs and isopropanol/xylene for business strikes? Or am I missing something? Report this Post to the Staff
psuman08 Pillar of the Community United States 1747 Posts	Posted 04/25/2023 10:36 am Nice results. I use my fingers to retrieve the coin in acetone as well. I have my distilled water dip next to the acetone, so the fingers get a good rise too. Report this Post to the Staff
Hordfest Valued Member United States 208 Posts	Posted 04/25/2023 1:04 pm 5 minute soak on a 1933-P. The reverse really cleaned up nice! Report this Post to the Staff
Hordfest Valued Member United States 208 Posts	Posted 04/25/2023 1:17 pm 1931-P 5 minute soak. My camera is auto changing the color on the reverse image for some reason so that color is not extremely accurate. Very odd. Report this Post to the Staff
Hordfest Valued Member United States 208 Posts	Posted 04/25/2023 1:23 pm First 24 hour soak. I'm going to soak this very dirty 1935-P for 24 hours. Around the date there is a tiny bit of mint luster which is hard to tell in a picture. Curious how this one cleans up. Will edit this post with after pics tomorrow. Updated!

Spence Moderator United States 34393 Posts	Posted 04/25/2023 1:54 pm @hord, this is an interesting experiment and I'm really glad that you are sharing your results with us. I do have one friendly suggestion though. It might be a little easier for us to see the difference these acetone soaks make if you put before and after images side by side into the same picture. You could use photoshop or an equivalent program to accomplish this. That would also help you to keep all pictures the same magnification. In this way, we would see the effect of the soak more directly rather than having to "remember" as we scroll down the pictures. Again, just a thought--the current format works pretty well too.

Hordfest Valued Member United States 208 Posts	Posted 04/25/2023 2:08 pm @spence fair suggestion but with the 300kb limit I'm worried that squeezing two coins into one picture will make them too grainy. I can try though. Do you know how to just post two pictures side by side instead of them stacking vertically using the [img] tag? Report this Post to the Staff

As such, it does not remain 100% for long and will have water in it. Inordinately fascinated by bits of metal with strange markings and figures Report this Post to the Staff

Yes Proofs should not need much and acetone will dehydrate and evaporate much faster. Lincoln Cent Lover! VERDI-CARE™ INVENTOR https://verdi.care/ Report this Post to the Staff

DOCC Pillar of the Community United States 1502 Posts	Posted 04/26/2023 03:01 am I have experienced rainbow toning on coppers with luster from time to time. I can't imagine I'm alone on that. Report this Post to the Staff
Hordfest Valued Member United States 208 Posts	Posted 04/26/2023 09:19 am Tried it on a 1956 Proof Penny. Did a long 24 hour dip on the proof. In some ways it's better but the luster seems less mirror-like. If I do a proof dip again it's going to be a very quick plunge instead of a soak.

Dearborn Moderator United States 94565 Posts	Posted 04/26/2023 7:40 pm There is a free photo program called "PhotoScape X. This is a great program to use for many things. one of them I use it for is to produce mosaics Here is an example of what it can do. (you can also specify the final file size and quality when you save a file.) If I can do this with ASE coins and still have them look good, it will be great for cent sized coins too.

Hordfest Valued Member United States 208 Posts	Posted 04/26/2023 7:48 pm Thanks Dearborn. Is there any particular reason why this forum still has a 300kb limit in 2023? Report this Post to the Staff

Yes, because this site runs mostly on donations and storage is not free. https://www.coincommunity.com/forum...upporter.asp Coin Collector Since 1978 Avatar Old Avatar 7070 Eisenhower Australia Canada World CCF Members on eBay CCF eBay Search Engine Report this Post to the Staff
