With one exception (the 2012 cent), all of the coins predate August 29, 2005. That's the date Katrina swamped New Orleans. In my opinion, at least some of your coins (1973, 1983-D, 1985-D) look very much like Katrina coins. The other coins just look like they have plating damage and bubbles and zinc rot.
The 1973 cent appears to have the tell-tale orange tinge of a chemically cleaned Katrina coin. The zinc cents have varying degrees of zinc rot. Copper coins submerged in the post-Katrina toxic soup fared relatively well. They survived, and could (somewhat) be cleaned chemically. Zinc Katrina cents had low survival rates and did not respond to chemical treatment.
We see Katrina (and now Harvey) coins in circulation fairly frequently around the Front Range. The orange appearance of the copper cents is a dead give-away. Having been in post-Katrina New Orleans for flood recovery assistance, I know the nastiness that Katrina coins were swimming in for weeks. Chemical cleaning or not, I don't trust them and don't want them around. I get rid of them as quickly as I can, and I readily admit to throwing some in the trash just to make them go away.
JMHO, but I think you have at least three Katrinas and all of the coins in your photos are spenders.
