Im Not Sure Of What Clear Materials Are Safe For Conserving Coins.

What specific items did you have concerns about or what type(s) of things are you looking for safe versions of? We can then make recommendations.

Pretty much anything safe for human food preparation is probably okay for coin storage. Things like Tupperware bins pretty safe for storing coins in especially like large proof sets, mint sets, etc.

I personally use museum archival products designed specifically for coin storage. Intercept holders and boxes for my copper/bronze coins. I buy from legit sources so I know I'm not buying counterfeit products these days, that is important I believe, so many fake products made to save a few dollars that could end up causing real damage in the long term.

Coins should be kept in low humidity, and darkness or low light, to keep them in the best environment possible. Check in on them regularly look for spotting, or any kind of color changes. In humid areas keep a dehumidifier on and desiccant packs near by, that are regularly changed out or recharged to remove moisture from the air.

Don't store them in overly warm areas, or near corrosive items, like ammo, solvents, etc. My coins in the safe are in close proximity to some ammo, but not loads and loads of it, also the coins are mostly in Tupperware bins or Pelican type cases. The only ammo near is a few magazines and mostly loaded into weapons also stored in the same safe.

May I ask how you want to store your coins? Individual or in bulk

So hard acrylic is fine for individual... and for bulk? Thank you for your responses...

Intercept is the brand I mentioned. It is available from dealers like wizard Coin Supplies, it's made of corrosion resistant materials. Intercept makes boxes, hard plastic inserts for their holders and storage boxes.

2x2 cardboard flips with the round plastic widow are still some of the safest long term. Make sure there are no holes in the plastic and the sides are stapled shut with no gaps. I've seen coins at estate auctions where the smallest gap in the cardboard leads to dark carbon spotting. A flat clinch stapler increases the number you can store together. And decreases the chance of a staple damaging the coin behind it.

Also there are newer non pvc vinyl that can be safe. Look for anything that says archival quality. They are more expensive. But I use those with coins that are too big to fit in the large dollar size cardboard flips. I buy cheaper vinyl flips for short term storage only. Like when I send a coin to a buyer on ebay. Or send them in for grading.
