I was recently taking photos of my coins and as I was reviewing and crop my 1945 I noticed a dot and discoloration below the maple leaf. Is this something I should be concerned about? not sure if it was there before and happened in the flip. thoughts? http://www.pieceofcurrency.com/Api/...8f1c3?size=1Thanks, --James Edited by qbvbsite

To me this looks like the start of a carbon deposit

will it get worst if left alone? No biggy to replace only a $46 coin but didn't notice that a few years ago when I bought it.

If it is a carbon spot it will get darker over time until it's all black

ahhh gotcha, will it spread? looked under a loupe and it must of been there before and I just didn't notice. Its actually partly on the leaf. Looks almost like a drop of something hit the coin at one point. Thanks for the info

It should not spread, if you keep it in a low humidity, stable environment. People seem to forget that while ICCS flips are relatively secure, they are not impermeable to water vapour.

Hey thanks for the information SPP. Well they are stored in a stable environment (68-72F) and I have central air for the summer. Humidity is about 55% down stairs and 60% up stairs atm (using my old dehumidifier) which seem high. My coins are downstairs in my fully finished basement in my old dresser. I ordered a few portable dehumidifier to put in the drawer with my coins. Think this should work even tho its not air tight just might have to recharge them a little more regularly. If not maybe I should move them to a sealed bin? Thoughts?

Actually might be lower left the dehumidifer on for a few minus and it dropped to 50. Maybe i'll run it for a little bet and see

I run a dehumidifier 24/7 in my basement, which keeps the man cave between 30-40% humidity. I use zip-loc bags as well.

Ziplock bags are a great idea... Also you can buy desiccant packs never a bad idea to use those either

Cool, I'm at 47 now after running for a little over an hour. Guessing its actually 50 (without it running). Going to get some humidity digital readers and place one of these Dehumidifiers and a readrt in each drawer and see what the readings are. http://www.amazon.ca/Ivation-Renewa...dehumidifierWith the ziplock bags do you put silica packets in there with the coins? Or would my drawer with those linked above do the same job? Thanks for all the information, never really thought about this before. Edited by qbvbsite

My dehumidifier has a drain hose which is fed into the drainage grate in my basement... so I never have to empty the container. Probably less necessary in the winter, but definitely works hard in the summer!!

I run 3 big dehumidifiers in the summer and back it down to 1 in the winter. I'm shooting for humidity in the 40's generally but it does vary from abt 35-50% with the 50ish in the summer if I get behind on emptying the buckets. :)

Wow 3 dehumidifiers that's a lot, Just running mine over night its sub 39-42 on average. Mine rating for 2500 sq feet and my basement is only 1450. Granted its almost winter now so humidity is naturally lower then the summer.
