1970 Coin Slab- If you collect PCI or ANACS photoslabs, you'll love these! Any info??

picked up two of these a while ago, not sure if I posted before so I am gonna try again, they are from error Trends Magazine. Certified 1970 in May. One is a 1967-P missing obverse clad layer and the second is a 1968-D missing reverse clad layer. Both have regular nickel opposites. they came in a soft envelope, similar to a currency holder. The coin appears to be in a non-pvc flip stapled three time each. then on the back, some how wax was applied over the staple reverse to prevent switching of coins. Each has a description of the coin as you can see from the photo, then authenticated by Arnold Margolis and signed by him in pen. One each top there is small writing 10:19:72- 100.00, guess that is what he paid. Anyone collect these?? Is there a market for them?? Thought they were neat so I picked them up. Any info and or value?? Should I remove them from the 2x2 as they are soft and most likely have PVC in them?? Take them out, dip em in acetone and put in 2.5x2.5 non pvc and restaple?? The back of the staples have wax on them to prevent coins from being switched or should I leave them as it??

Edited, I wanted yopu to be able to read everything and see the coin in all of its glory and I have no freaking idea how to make is smaller or larger. I just take the pic and load it into tinypic.com.

<< <i>Those are neat certificates. I have picked up a few of them in the past. They are not archival quality and thus the coin runs the risk of damage due to storage. Then again, if you pop out the coin, the certificate loses much of it's collector interest. It's quite the pickle!

Agree. Those flips look like they are starting to deteriorate. They're probably made of PVC.

I bought it because of the design and denomination bearing the cud, but also because I had never seen such a holder before.
I think its a neat item to have, and reminds one of the "primitiveness" of the hobby just 40 years ago!
