What Exactly Is 'Thermotron Sealed Strips"?

The clear plastic seal that the RCM uses (sometimes) to package the coins for distribution.

"Thermotron" for the plastic material, and "strips" for a number of the sealed coins at a time

example on ebay:
a RCM thermotron sealed wolf

"strips" of gold panda coins

Thank you for the clear explanation!

So does it worth more if it has the RCM logo like that in the first ebay listing?

HAHAHAHA Ya thats right...If they exist. Still have no idea. Can't seem to find that answer anywhere and the mint isn't helping me out much. I thought another member of CCF had said that he finally got enough coins to bring to the mint and have them sealed. I asked him to verify what he meant...but no response. Again, for most dates, having them in RCM packaging will get you a few extra bucks. When you get key dates such as 1997 sealed you ca get another $10-$15. Availability is key thought! People pay more to get what they cant find. So you aren't going to get as much for say a 1997 SML if there are 15 others up for auction as if there was only 1 or better..NONE. Though sometimes if you want to add to a set you need to throw the price guide aside and do what you like. My set to me is worth more than the money I paid for them and I have had to pay for that coin that I really wanted but LOVE that I have it. But that's a bullion collectors stand. If you are just doing investment silver is silver and buy as CHEAP as possible. Bulk buys of 10oz or more will usually get to a better price per coin. Seems that you can buy for say $3 average over spot per coin and sell on ebay for about $8 over spot. But remember they have fees that usually after all is said and dont will cost you about $2.50 for every $40 made. CHEERS! P.S. Watch for that 2009 SML for me! :-)

Thats right... milk spots can still happen. Most of the time there is a micro crack in the mylar which allows air or moisture to get in. I have the wildlife series all in mylar as well but I also try and protect them even more. There are 4x6 acid free hard cases that you can find that have a small pad inside them so when you place your coins in them it stops them from moving around. I also find that the mylar cut out of a sheet at its largest would need a 3x3 space to fit them. I place 2 coins of the set in 1 case. The case also joins with a tounge and groove seam which helps seal it once more. Sometime down the road once I have the set complete to my liking I will have it vacume sealed as well. 3 times sealed to try and prevent anything from happening. But that is for personal collection and a really nice way to try and preserve and display at the same time. I think bullion sets are still wonderful regardless of the mass number of people on this forum that still referr to bullion as JUST BULLION and not a collectors item. To each his/her own. Personally I dont care about old coins and think that they are a waste of time but I respect the history and rarity of them and also respect that they are what they enjoy collecting. So good on them. Sorry about any spelling mistakes...not my strong point. :-)

Closer to $6.

OK, then is it better to get those air tight plastic cases?

I'm getting air tite cases just for coins I display. Most likely will display one of each silver bullion from around the world, the wildlife series, and pandas.

Everything else will either be in tubes or whatever packaging they came in.

Its a nice looking set Poboxw.
