Looking very carefully at the photos of these contacts, I believe they're simple
tinplate. This would fit with the inexpensive phenolic PC board material being used.
Kepro makes a non-electrolytic tinplate solution that comes as a dry powder and is mixed
with water. It works well enough on bare copper PC boards to provide a
corrosion-resistant coating.
