When I got my PC Molly from an original collector on eBay, her glasses had tortoise shell plastic frames. I thought nothing of it and never replaced them with the silver ones.
An inquiry on AGIG noticed Molly's glasses were different on the BF Molly books. They look like my Molly's frames, not silver.
While it's difficult to "predict" AG decisions any longer, I thought it was still interesting to point out.
