Really? I thought I was on the high side for prices. These are my last Mexico 8R purchases by type:
$300 for a 1652/1 8R cob at Ponterio's, but that was few years ago (full date, cleaned I'm sure).
Last month a couple lots of 8R Dos Mundos set me back about $200 per coin from the Stacks Bowers Ponterio auction. Take out the rough one, say $225 per coin, some cleaned.
This summer at Coin O Rama in San Diego, 10 8R portraits cost me just under $300, figure $30 per coin, cleaned, some chops. I got a nice 1787 8R at the spring Long Beach for $55.
Today I bought a 1849 Ca RG 8R with a cool die break for $39 at Treasure Trove in San Diego.
These good, not great, deals for coins in around fine condition.
