Right side of the obverse, possible greaser. Grease or debris filled die, lack of letters and date on that side.
I would say a grease filled die. Grease from the coin press got on the die and filled in the letters and through a progression of strikes, smoothed out the die face in that area making the letters disappear.
To me they are worth $20 each. They are just modern replacement notes. Other people may say differently as to their value. But I spend them. You can look them up on a star note website, to see how many were produced. Maybe if it is a "short run", and maybe if you have a note of superior quality, there could be a premium. But not to me.

Well, the Buffalo Nickel with only 3 legs was a filled-in die and it was worth $1000's. What's the difference?
It should be easy since the leg is a depressed feature in the die. One can polish the area around the leg to where there's no longer a depressed feature.
What about the six claw bear paw? I've heard it's just a die chip on top of the paw alongside a claw so it kinda looks like 6 claws. It seems like it might be pretty popular.
Minor die chips and filled dies are very common error types. Occasionally, they will occur in an interesting place that allows somebody to try and market them to new collectors as something special. Unfortunately, the majority of experienced error collectors understand that these coins are not rare or valuable. Experienced collectors and dealers will purchase your 1955 doubled die or 3legged buffalo, but if you want to get any premium for the RUST and 6 claw errors, you'll have to find a newbie who has fallen for the hype. They are cool finds and I would keep them, just don't fall for the "valuable" marketing gimmick. Hope this helps.
That is exactly how I feel and what I thought, which is why I paid very little for the "six claw bear" quarter I bought. It was part of a multiple coin purchase so they all shared in the shipping.
