SuperSafe Self Sealing Cardboard 2x2s

Anyone use these things? Thoughts?

I prefer the dangers of staples. I learned not to allow glue anything, near my coins. Just my dos pesos 😉

I can't comment on this specific brand, but I avoid self sealing 2x2s. Unless you know the type of adhesive and whether it can migrate and/or off gas to the coin, and how that residue would react, I would not use them. Just my opinion, and I have no hard data to support it.

Be careful with cardboard 2X2 coin holders. The windows have microscopic dust particles from the manufacturing process and can spot your coins especially red copper. Before you use them, wipe them clean with a clean cotton cloth such as a T-shirt or you can blow off the cardboard dust with compressed air.

I don't want adhesives near.my coins.

If you use the staple 2X2 cardboard holders, be sure to flatten the staples with a pair of pliers. I remember a coin show from the pre-slab era. I asked a dealer if he had any $10 gold Liberty coins. He pulled out a box crammed full of gold coins in 2X2 cardboard holders. He pulled out a nice uncirculated $10 gold coin and handed it to me. The plastic window had a vertical tear and there was a scrape mark running down the obverse from top to bottom. He had so many coins crammed into that box that the staple from one of the coin holders severely damaged an adjacent coin in the box. Seeing that left a lasting impression on me.

I bought a couple boxes many years back. Not sure what brand they are. I did not really use them, I did not like that they were very thin. Because of the thin cardboard I did not feel that the coin was recessed and protected enough. I did not even think about the adhesive and possible chemicals.

Yes, have used and have several sizes for future use as I do like them. I blow them off with a bit of air before putting a coin in. They seem to work just fine.

I've used 2x2's that require staples as well as the ones that have an adhesive that can be pressed shut. I've settled on a simple 2x2 flip. .. no staples/no adhesive and I haven't had a coin fall out of one even if I've dropped it .

COCollector

Instead of staples, I just thought of another option:

Of course, packing tape is trickier to use than staples -- especially achieving a tight seal. That said, nowadays I rarely use 2x2 cardboard... so many better options (plastic flips, capsules, self-slabs, etc).

@COCollector.... The adhesive from the packing tape may penetrate the holder. It does eliminate the staple danger, which is great. Admittedly, the tape is external, however, chemical outgassing is a tricky phenomena. Good luck, Cheers, RickO

Heard a noise and traced it down to grandson and new item. It works, is rechargeable, has just the right pressure for “ leaf blowing “ the flips. 😉

I use Saflips and seal them with an impulse sealer

Before getting into albums, I used the hard plastic 2X2's for my dollars. Costs more than the cardboard but better protection. Dropped several and never popped open or damaged coins.

I'll stick with the staples as well

I used some of the self sticking type back in the 70's and still have some of them with no apparent ill effect. But it is mostly circulated IHC's and merc's'. The regular staple type also worked well even on Unc. coins put away 40 years ago. I did learn that if you sealed up a coin from circulation that looked Unc. they could get spots or fingerprints showing up later.

I have some from the 90's that have no issues but yeah they are on the thinner side.

What is with the strange and apparently somewhat random bold text?

If you indent everything with 4 spaces, it turns into a code block like this:

I copied and pasted from the web page.

If I indent 4 spaces on each line,
will my post be formatted as a code block, with key words in bold?

Yes, as it turns out. Spooky cool!
