My records indicate I paid $130 total for my PCGS MS64, purchased off eBay, already in the slab. Seems proportionate for the additional three technical grade points. Without checking the KM value offhand, I reckon each of our two coins was an equally good value for the money. PS- I do note my coin previously sold in a 2019 Stacks-Bowers Hong Kong auction for $85 before fees.
Sounds about right, yeah. I do like the toning on yours. Awhile back there was a really nice toner on eBay, raw, but I was outbid. I think it went some north of $100.
