I found a ring today and I thought it was sterling. However, it is marked 417. This is the mark for 10k. gold. What is
strange is the it rang up 82 or 83 on the AT Pro. It also has some tarnishing on it. I did an acid test and it tested positive for 10k. Anyone ever ran across this before?

Thanks for the comments everyone. I've been lucky to find more than 30 gold rings but never ran across one with a VDI number in the low 80s. All my gold finds have been between the upper 30s to the mid to upper 60s.
