I hate to be the new guy who comes in at a low price, but Ichiro has been signing a lot lately, which has been driving down his prices. Though $500 may be an accurate amount for what this would have been a year ago, I think it is a bit high. Pleanty of 1/1 Ichiro Autos can be had for under $500, plus this is a redemption, so even though he is signing a lot now, maybe he slows down and this never gets made.
Redemptions also always go for less than the live card.
All of that together, I would say probably in the $300-350 range. If someone offered you above that I would immediately pounce on it.
