When my father was in China in 1944, he bought and brought back a "coin". On the coin were pictures not fit for children to see so he soldered over them. I know this coin is at least 67 years old and I would like to restore it and possibly sell it to a collector. Any ideas how? Your help, as always, is much appreciated

Coin material? Copper? You are gonna have fun. You can either use a plumbers torch dirctly on it and see if the solder melts away orrr..... get some multistrand wiring(the finer the better) like what is used in cars. Peel back the plastic and inside is a multiple of fine wires.. There is also something you can buy at the electronics store called solder pic up and it is braided wire in a band like tape. You then need a soldering iron which you place over the braid which is in contact with the solder. You are trying to heat up the solder thru the braid. The solder moves toward the heat source. And you pickup the braid and iron together and see if the solder is dabbing upward into the braid. move on farther down the braid and repeat the process If it is a copper, the solder will remain. You can't get it all off as much as I am aware (I have never needed to do so)

with this tight a spacing it would be best to start with new stuff. Elbows and 1.5" pipe. Cold fit everything to be sure it fits.... then put on soldering paste to the surfaces and refit everything, then heat it all up and touch the solder to the pipe until the pipe melts the solder(not the torch flame.) 1 joint,2 joint,3joint,4joint - done. Walk away and have a coffee and let it cool. Removing the solder is not an option. Takes too much time.

Use a soldering gun that is solder-free on the tip. Heat up the gun and stick it on the solder. Solder will always flow to the hottest point! Wear gloves. To wipe the solder off of the tip, I always use a damp rag. Works like a blessing!!

try to determine what the metal of the coin is. solder melts at a relatively low temperature. if coin has a higher melting point melt it off with a torch

Use a butane (plumbing) torch and a moist (not wet) paper towel.
Gently warm the coin with the torch-use heat sparingly-after a short interval blot the coin with the moist paper towel-should remove it-take your time-don't burn yourself!
If in doubt consult your local coin dealer for advise
