Indecisive: Coin frame, capsule, foam

[Curtis JJ]

Those quadratums look very good, so does @Etcherdude's "slab"! I like to use the round capsules with a foam "gasket" then put it in a 2x2 flexible high-plasticizer flip (since I'm assuming they're protected). The best fit is Byzantine gold and Roman bronze coins, denarii (incl. Republican) and Ants. Almost everything Greek, RPC, too thick (besides Greek "tinies"; Sestertii & cup coins, nope).

One thing I like about the capsules (some of them anyway) is that I can affix a thin adhesive note to the edge. E.g., An inventory number that leads to complete info for a coin. Or, as below, I'll write some bit of provenance info on the label that will surely lead me back to my original cataloging:

I have received a coin from Roma, London. Normally Roma sends the coins in a small jewellery box. This time I got a holder that I had never seen before.

The whole thing is called a floating frame.

A frame that you can open and close and that has a very thin (almost sticky) membrane in both frames. This is where the coin is inserted. The coin does not slip here. Then you close the frame and the coin stays in the middle.

It doesn't matter how small the coin is, whether it is round, oval or square. The thickness does not play a primary role either. I find these frames very fascinating.

I found these hover frames in all sorts of shapes and from many manufacturers on Amazon. But they should also be available elsewhere, perhaps even more specialised in coins: https://www.amazon.de/Cabilock-Floating-Displayhalter-Display-Challenge/dp/B08CKPKS3T/ref=sr_1_16?__mk_de_DE=ÅMÅŽÕÑ&crid=36TNOVF4VG54R&keywords=schweberahmen&qid=1659429866&sprefix=schwebe+rahmen%2Caps%2C133&sr=8-16

Yes, I got those too. They take up too much space for the regular collection, but you can put them upright and present some of your coins e.g. in a showcase.

I bought a few of these from eBAY to display a handful of coins I also place a small piece of card with attribution etc. inside. One caveat though is that I put the coins in a plastic Lighthouse coin capsule before sealing them. The reason being is that I have no idea if the thin membrane is coin safe. My basic rule is that if the plastic is flexible it is too risky to come in contact with my coin. I don't know if my concern is valid or I am being overly fearful. 

Another thing about these holders is that the membrane will absolutely pick up any grime/sweat from your fingertips, you need very clean hands to handle them.

I was wondering the same thing! Is this membrane acid-free? Is it good for coins? Unfortunately, I can't find any information about this on the internet.

I ordered floating frames from Roma and I use them not just for expensive coins, but also coins that I just like that will display well in a floating frame.  The downside is that they are somewhat bulky as holders go, and there's no place to insert the coin's label. That's why they are used in conjunction with Roma's boxes.  I think a basic workaround would be to simply tape the label to the back of the holder.  Storing numerous coins in black boxes can be a challenge in figuring out what coin is in which box.  They really need some kind of identification on the front and arranged in a logical manner when stored.  That's a challenge for me.  I can't even organize a closet.  So I might eventually jut store the floating frame stored coins in a 2x2 box, with their label taped to the back of each frame.

The vast majority of the coins are in 2x2 safety flips.

Here's one of my coins in a Roma frame.

Got these from Roma  2" X 2", fit my 35 mm NewStyles,  of various thickness of coins.  good enough for me.  Ancient coins are ancient coins  and have had a lot of travails in their time.  They were generally mass produced practical things  not national treasures!  The Roma things fit into a carry tray!
