I am assuming you are speaking of mint-sealed bags- The fabric in these will in time create some problems for your coins. I have in my earlier years gone through many bags- and left some in- Well, I can tell you- Those that I ran through a coin counter and wrapped in bank rolls then placed in air tight 50mm WW11 AMMO boxes --picked up at war surplus stores- has proven to be my best storage. I have opened up some rolls that were put away 45 years ago- and they still have that brilliance- You won't always get that in the bags because air can get through- If your only concern is for bullion type coins- then no problem- you still have the intrinsic value- My Two Cents worth--There are other solutions probably as good.
