    Well, I went out and bought a vacuum sealer and sealed all my Silver Eagles. I know many members have recommended this to eliminate the dreaded milk spots on these coins. I did not seal the ones in NGC/PCGS holders as I did not want to crack them open since they are graded coins. My question is have other silver coins developed these milk spots? I have a couple of the buffalo commemorative dollars and wondering if I should seal them as well.
    Thanks your advise.

    Dont know about using the Vaccum on coins, but my As Seen on TV : EuroVac 2000 works well on both steaks and fish.

    Hi, i don't have an answer to your question. But i was wondering if the plastic sealant is chemical free, so it does'nt pose a threat to the sealed coins? Or does the vaccum eliminate the danger? Thanks!

    That is a good point. I have seen a lot of members saying they are doing this so I thought it may be a good idea. I notice the plastic bags are made in Korea. Now I am starting to second guess this strategy.

    I don't recommand it at all. Someone in another forum did an experiment with BU Washington dollars to see how long they would preserve but they didn't even last any longer than 2 months. It might depend on the type of plastic that you use but again, I don't see what good it is. You might as well dump your coins in the fridge so that the rate of reaction will slow down. :D

    Wait, are these the proof or BU? If they are BU, I wouldn't really recomend it, cause after a period of time the coins will get some marks from the plastic on them. Proofs, whatever you do, don't put them in. They start to get hazy, develope spots, and man do they look horrible. The best thing I can recomend honestly are airtite holders, while they might not be perfectly airtite, they still do a pretty decent job.

    Thanks everyone for the advise. I think the concept may be ok given that I have seen coins preserved in plastic ('Chinese Pandas) come to mind), but you are right in that how can you tell if the plastic is safe. Also, never thought about the marks from the plastic. Guess I'll take my chances with the airtite's and cross my fingers.

    Phoenix,
    I did put some proofs in (although it was just overnight). Would you recommend just taking them out or should I take other measures? I have also read that some members dip their coins in acetone. I would thinik that just having them in the sealed bag overnight would not be long enough to damage them, but now am getting paranoid.
    Thanks!

    Dealers put silver coins in PVC flips for short periods of time - all the time with no noticeable effect to the coin. I'm sure you are fine overnight.

    I would wonder if the PVC issues are just from direct contact to the silver. If you put yours are in air-tites and then in sealed plastic I wounder if there could be any effect regardless of the plastic type?

    Good Luck

    PVC is only an issue when it starts breaking down and release it's nasty chlorine gas. You know what chlorine does to you if you swim in a swimming pool for an extended period of time.

    I would recommend to take them out man. I had some silver proof State quarters I put in bags that sound like you are talking about, At least PR 69 material honestly, and then a week later I looked at them, they fogged up, got lines from the plastic on them, even more I can't remember right now, was about a year ago, but to put it plain and simple, they were a mess. :D If I were you I would take them out, and buy some airtite holders for them is my advice. They shouldn't be too bad only being in there overnight, but I'd take them out before something does happen. This is all my advice, and others may disagree with me, but I'm just trying to help some so they don't make the mistake I did, and losing a good some of money in the long run. But some bags might be okay to use, but all I know is most of them aren't something I would store any coin in. What kind of bags are they if you don't mind me asking? Best of luck man! :thumb:

    Again, thanks everyone. I really appreciate eveyone sharing their knowledge and experiences on this subject.

    Phoenix - I am not sure what kind of bags they are. They came with the sealer (Rival brand if I recall).

    If the bags were intended to be used with food then they contain no PVC. However, this is a practice that has long been used by many collectors, and it works quite well. But it is recommended that you use non PVC coin flips instead of the bags. They are already sized correctly and it just generally works better.

    I used a vacuum and it sucked the coins right out of the bag. :eek:

    I like the idea of putting them into Air-Tites and then using the vacuum sealer.

    Oddly enough, the plastic pouches the Chinese used for the Pandas are made of PVC. Or at least the early ones are I don't know if they ever changed or not.
