so again i have to open three of my boxes and put them together into one bigger box to accommodate 12" x 12" x 36". so it will be a rectangular box. what about other sizes and put together it will be 3 cubic feet?. now i understand. thanks again gdjmsp.

1. my oven is big. by inserting small silicon pack 40 gram there for three hours at 300 degree high. can i put some other stubs for cooking with that?.

2. my other 24 pcs. silicon gel. it might be good for one to two weeks. if it was done. i forgot to take it out. let's say for few months. can it affect those coins inside?.

i like you gdjmsp. you are so nice. i keep bothering you. is it alright?.

can i put 4 -40 gram silica pack at the same time for re-activation? or i should put inside there longer time than three hours for four packs?. the reason is that it will save some electricity bill. each time you use 3 hours on an oven at 300 degree will cost you at least 0.75 electricity bill in new york. that is the same cost of one silica gel. sorry i usually use the word silicon instead of silica.

i discovered that by using sandwich bag to cover every coin holder or capsule or sleeves. it works too. all my coins were inserted with sandwich bag (non chemical sandwich bag). for fifteen to twenty years. all my coins were still brilliant. except 25 coin of my 1992 american eagle proof dollars where i mistakenly used plastic bubble (for protecting things inside a cartoon box). those coins were easily gets black spot. and i took out those original eagle holders out to save space. that's another big mistake.

many year before, when i started to collect coins. i also got sticky materials from inserting most of my circulated silver dollar coins inside the pvc 2 x 2 holders. well, those time really no body knew that. same happened to stamp collectors. that we used to insert old stamps with sticker or glue and attached to the stamps booklet. it destroyed all the collection.

 

As I've said so many times before I have had coins in Whitman Classic Albums inside plastic baggies with as much air pushed out as possible for well over 50 years. Many coins in plastic rolls sealed with Scotch tape. All look just as they did when first put there. Out of 10 Licoln Cent sets, for example, none have any corrosion, toning, spotting, etc. If no or little air gets to them, then obviously nothing happens to them. This may not work for hundreds of years and I will let you know about then if there is any changes.

 

The way silica packs work is very simple. They absorb the moisture from the air until they become saturated. You can easily recharge them by putting them in an oven on low heat until they are dried back out.

 

miracle?....

i received another 12 silica gel today and continue to open those remainding small boxes. so that i can put silica gel to it. i found out that 25 pc of my 1992 american eagle proof silver dollars were back to brilliant proof. without any black spot whatsover. it is a miracle. because those proof coins gave me problems and from that time on, i never order or buy proof coins. why i got black spot. because i took out the 25 coin with origianl capsule and put it all coins together to save space. all covered with white plastic bubble protector. after years of storing. when i opened it two years ago. all 25 coin got black spot all over. so i put small clear plactic sandwich bag and covered every coins and capsules with it and put back to original american eagle proof boxes. after two years. today i found out all spot were gone. it is a miralce. thank God.

 

discovering

did i discovered a cure for black spot by covered damaged coin with clear plastic sandwich bag on it for few years?. i really don't know. you can experiment it.

 

Damage just doesn't go away...it must have been something else.

Damage

I Mean Damaged By Black Spot All Over The Coin.

 

But damage just doesn't get up and walk away...even slowly...there is something else that isn't coming to light.

Tracy5900 what speedy is trying to tell you is that the black spots on the coins, if in fact were on the coins, did not just vanish or walk away. If there were black spots on the coins, they got there by a type of chemical reaction with something and such a reaction is not reversible. In order to create the black spots, part of the metal has to combine with something. Black spots leave and so does part of the metal.
Me thinks your not telling whole story. Or someone is playing a trick on you.

 

plastic sandwich bag

i think sandwich bag protect the coins forever. remember it protect the foods. no chemical were there whatsoever. or else we eat foods everyday. if something wrong on those bag. people already sue those companies. i am so happy that those 25 proof coins of mine still shining without black spot. i hope someday. collectors will discover new ideas to protect coins from black spot or tarnish. and i think clear sandwich bag can. it protect the coin as well as the envelope, case, certificate and specification card, and carboard box. protect from being dirty and paper being change color. all my u.s. mint products were covered by clear plastic bag. it looks like you just bought it from the mint today. now i ordered a lot of nickels and quarters rolls. all coins will be transfered to coin tubes and also cover with sandwich bags on each coin tube. now i even add silica gel and silica pack. idea and knowledge from coin talk forum. and specially thanks to gdjmsp and speedy. you two are the most needed persons on coin collecting.

 

cheaper silica gel

i check the web and found out that bulk silica gel ( 5 pound) or (2,500 gram) cost $17.50. this come out with a jar. it is reusable color changing silica gel. blend with 10% indicating beads and mix with 90% clear beads. 2,500 gram can be put into 200 small silica gel at 12.5 gram each. thus each 12.5 gram silica gel will cost eight and 3/4 cent each. if you buy from coin supplier. it cost you 67 cent each. that will safe you a lot of money. my problem is how to get the thing for inserting 12.5 gram of silica gel. anyone knows?.

 

Cedar hope chests, display cases and humidors are very good for storing coins. They are expensive, but worth the investment. Cedar wood absorbs the moisture out of the air like a decessant.

As a precaution, you can also put decessants inside of the case.

 

Good to know
