I just discovered something that while totally useless might be helpfull to some people. I recently purchased a half dollar. (For those wondering, it's a polished 1942, and yes, I knew it was damaged when I got it) and I have had it sitting here next to my computer since I got home from my trip last weekend. Well, I also used 4 camera cards on the trip. My camera takes SD cards. Well, I had left one of the camera card holders open. I discovered that the half dollar fits inside the tiny holder that SanDisk provides! Useless? Probably. But I feel like I've made a coinage discovery, and with the way my day has been so far, it's actually the highlight! Who knows, maybe somebody could use that info for a good reason... I actually decided to take a picture.
Nice... Next time I find an old Franklin in the woods while hiking and I have my camera bag, Ill know exactly what to do.
Billy, Don't undersell yourself, my man. That's absolutely fantastic. Seriously...that story and pic deserve a Coin World article.
Those are the small plastic cases I drill holes in and put in some scoured new cents to collect environmental damage gases and protect my coins in boxes. Works like Intercept(tm) method, but free as you can spend the damaged sacrificed cents. Does anyone know a source ( other than buying a lot of SD cards, which I have several)?
hahaha! I was just thinking how long before someone is selling these on EBay as coin holders. Brilliant!
Well I actually did find sources for them on a google search. The ones that do mention the plastic, it is polypropylene, which is safe for coins. Mine tend to match the polypropylene CD/DVD shells I have from Derling.com, so I think most would be. Jim
Some of these replies had me laughing! DesertGem, how do you know, or can be sure, that the environmental issues will attack that coin only, and not attack that coin in addition to the coins you don't want it to attack? That's a very interesting idea, and I may have to appropriete it. I go through a ton of camera cards...I don't reuse them, I buy new...so I could spare a holder or two.
Well I don't for sure, but the odds should be similar to an Intercept(tm) type of solution and somewhat better as they are replaceable. If the owner doesn't recognize that the sacrificial coins are changing and replace them, then the other coins can be affected. Raw surface metal reacts more actively with sulfur and oxygen than coins with a patina; even modern copper after a few days has a thin protective patina on it. Some reaction could occur with the "good" coins, but if the effect is reduced by 90%, it has done a good job. Ziplock bags would be as good by themselves, but I like to have some coins in albums and 2x2 boxes to admire and play with them. Try this. Take a few modern change cents that are close to BU, scrub them well till bright and shiny. Lay a few outside in a sheltered place, a few inside open to air, and a few in a ziplock bag. Compare them after 2 weeks and see if there is much difference. Results depend on your local air, but it will give you an idea of corrosion danger. Jim
You made me go look at my card cases. Are you sure your talking about an SD card? Of course like anything else different manufacturers do things differently. My SD card cases by Lexar are rectangular. Same with my XD card cases by Fujifilm. However, my SanDisk and Lexar CompactFlash card cases are amost square but still a little rectangular. Still a good idea.
Carl, I am a semi-professional, published photographer who has been using SD cards since 2003, and have used more then 200 of them...trust me when I tell you I know what I am takling about! This is a new style holder, it debuted about a year and a half ago, and can hold SD or XD cards. I'm not that big a fan of it for the cards, I preferred the first style they used the best, but nobody is using them anymore, at least that I can find. I'm pretty sure these came with the SanDisk brand cards I prefer, but they might have come with the Dane-Elec brand, which I am not too fond of...but most of the companies are using this new style now. The one good thing is that it takes up less space in my storage container, and I can fit more cards in, with the old style the flap gets filled with 3, the new style it can fit 5 or more (I have not tried more then 4 at a time and there is still space). I could fit a lot more if I didn't have to use so much space for CRV3s, my camera has a tendancy of eating them, so I always keep at least 6 on me, to be sure. That is a very interesting idea Jim...I think I will test it myself! I wonder if silica packets would also be beneficial?
