To Open Solid Roll Or Not?

It depends on you. Will there be more ROI should you find one variety coin vs annual appreciation? Maybe worth looking through if it is more at that point.

Me: I'd want to search them. But my view is based on nickels and cents. I picked up 5 rolls of unc 1960s nickels a while back. I ended up cracking the OBWs to look and found a couple DDRs. Ended up being the right thing to do on my end.

Good luck!

I believe that's the case. Sounds like the expansion series for the 2004/2005 nickels. I see them for sale on ebay routinely and they are solid rolls.

For coins with details on the edge, seems to me that you should wear soft cotton gloves and minimize the touching as best you can. Flips are fine to keep coins from most exposure to the elements, but anything significant should be encased via other means. But it really depends on what you find. Hopefully another CCF member with particular knowledge on dollars will chime in here to give you better advice.

You may be right about the air-tites, but I suspect they will lock out the elements that flips cannot. I've not used their product, so I can't really speak to either the loose fit or if they are indeed, airtight. But others here have attested to some degree that they work well in locking in freshness.

Flips do have that sandwiching effect where it traps the coin. But gaps between layers might allow air/moisture to get to the coin. They sell adhesive backed flips I think, but adhesives will breakdown over time making me suspect on the overall protection in the long term. This all said, the more important/valuable finds might warrant a better solution than flips, but for many coins, the flips afford a reasonable amount of protection over the short term.

NOTE: I routinely cherrypick the LCS inventory and I see multiple flip types and ages used to house coins. I've seen many BU coins that didn't fair well, so this is why I stress that higher grade/value coins should be housed differently. Storage is important. Many coins have lost half their value/interest with all the spotting and corrosion from the elements being trapped/getting inside the flip. Over the years, the inventory is depreciating because of the storage method and the owner knows it. And you see the sad stories here. So do your due diligence and make an appropriate decision for your collection.
