I received my Rittenhouse Rewards card last month, and noticed that the material/coating on the corner seems to be peeling off. It is very odd. I thought I heard someone say that this was also a problem on the chase in the most recent Bond set by Rittenhouse. Anyone know ?

Yes, the Quotable chase set for the Bond Autographs & Relics set had several 'peeling' cards. The quality was quite poor.
I got the Rittenhouse Rewards card for that set and it was actually in perfect condition, but the pack-pulled Quotables had several faulty cards. I know other members had the same problem.

I'm not sure Rittenhouse have commented on the issue..yet.

My rewards card had very slight peeling, like the last two cards in the quotable chase set.

Noticed this light peeling too.

Also the QS22 was sent in a toploader but no "penny sleeve" so it was free to move around a bit during shipping.

Not complaining but these rewards cards fetch higher prices these days so maybe Rittenhouse should sleeve them before shipping?

Mine was the same. I contacted them and sent it back for another, which was fine.
