Coin Conservation 1940 Proof Walker

so that is why the walker I bought looks like that. The photo showed MS details but in hand there is no luster. I knew it was improperly cleaned, and now I know how.

@LostDutchman what product did you use for dip to achieve these results?

I use E-Zest when dipping.

 

How long was your dip time for this one?

 

5 seconds give or take

 

I do too. If it's raw and particularly if it's circulated, it's almost certain to have something on it that needs to come off.

 

What is the actual process you use when dipping the coin. Obviously, you want to bathe it in the solution and get full coverage. Do you simply gently lay the coin in a container of the solution and then pull it out after the appropriate time? If so, the coin is obviously lying on of it's sides...does that affect the result on that side?

On the flip side, if the coin was suspended in solution (either my a gloved hand or some kind of holder)...a portion of the coin might not get exposed to the solution.

 

I use these. You can grab the coin vertically and maintain good control over it.

 

You a dentist, too...? ;-)

 

hahaha! no

 

That's called a ring forceps and is more commonly used in gynecologic applications (Just what Matt wanted to hear, I'm sure! LOL)

 

That makes sense to me...almost looks like a pair of Magill's Forceps. I have several at the office.

 

Not sure if this was for me, but acetone is the last step...

 

Me too... I just conserved a silver Chinese coin recently that had some PVC residue. I soaked in acetone first for around 10 minutes which loosened up the PVC. Then a quick dip in the E-Z-est (at half strength mixed with water so I can better control it). Then a very good rinse under tap water. The last step for me is another dip in a clean batch of acetone where the coin is swished around well in the acetone, then I simply set the coin on a paper towel and let any remaining acetone evaporate. I flip the coin over on the paper towel after 30 seconds to a minute so the other side gets plenty of air to evaporate too. I'll then inspect the coin for any remaining residue... if any remains then the process is repeated... if there is no residue, then the work is done.

 

I'm a little paranoid about the industrial grade acetone I get at the local hardware store, so my last rinse is in distilled water before blotting. But that's just me.

Oh and be really careful about acetone fumes, the stuff is toxic and explosive. I put it in a pyrex dish, put in the coin and cover with a small glass plate. When done soaking, I keep it covered and carry it outside (minus the coin!) and pour it on the driveway . It evaporates almost instantly. You really do not want to inhale that stuff.

 

PF 67 They just posted it.

That ROCKS! Nice job.

 

Looks good. Congrats on the 67!

 

Matt, maybe it is the light, but the final reverse seems to show more visible damage between the eagle's legs than the first. Is it just the lighting or physical? I can't tell from the photos.

Jim

 

Well I guess it doesn't matter Congrats!

 

I think it's the lighting but I'll double check once it comes back in the mail.
