I have a 2005-2006 UD hardcourt hardwood signatures of Raymond felton 16/50. this card was a redemption and I don't think there are too many live because I have only ever seen one on ebay. BV is NA due to scarcity but I would guess BV would be about 150 compared to the ones that do book. I would be looking to sell make an offer
I picked up an Ellis for 40, and one just sold for 20... I bought a 1/10 Felton auto sweet spot for less then what you are asking... I will have to pass... good luck
