The PCGS Price Guide and PCGS's Coinfacts cite prices for conditions G4 ($54) through AU55 ($850). As everyone knows the Price Guide is just that, and the market can be very different. For example, an AU55 sold at the 8/12 ANA for $5175. (It is the only auction listed.)
To view the JR-8 1829 bust dime on the Price Guide click on the "plus sign" icon next to PCGS coin number 4511 (1829 Small 10c). Die marriages drop down. The JR-8 is PCGS coin number 38833.
Coinfacts offers a more complete summary. Here's the link for the JR-8.
It appears PCGS has graded only two JR-8's (where the attribution was paid for). Others may have been graded but not attributed.
