Quarter weight missing one clad layer = 4.71 g +/- 0.347 g; missing two clad layers = 3.75 g +/- .467 g
I'm thinking annealing error. Show a close up of the reeding. Maybe @Fred Weinberg: could give opinion.
Gold plated. Lots of plated sets were sold on the shopping networks and From magazine/newspaper ads. They targeted new collectors. Over time, people found out they were never "prized heirloom" and some got spent (at least they were able to recoup a small part of their investment) It's not an annealing error
Lots of these were gold plated back when the series was running. What does the the reverse look like? If it too is the same color, you likely have a gold plated quarter.
