I do not believe there is Zinc showing...how ever it is weird that some of the copper color is showing around the bay 11 area. If you look in bay 10 of the first coin you can see the top of the pillar doubled. There are a few other spots that are showing copper on the obverse under the bust but there is a lot in Bay 11. I gave them a quick acetone bath so maybe there was debris in that area.
