So far. These items are extremely sensitive and no one but a trained specialist should go near them.

If the human race goes extinct due to global warming or whatever reason, at least we left these artifacts behind.

that's unfortunate of course. it's almost certainly going to be able to be restored though. I wouldn't put the frame of a piece of artwork into the "priceless" category though.
