Does Topps ever redeem expired redemption cards?

I have seen some unredeemed and expired cards on ebay and wonder if they are ever worth trying to send in (specifically to Topps)? Anyone know of successes doing this? I have heard Panini is good, but nothing about Topps.
Looking for rare Randy Moss rookies and autos, as well as '97 PMG Red Football cards for my set.
