Nope---the value is $0.25--grease filled dies are not rare and even I have found a few...a know a guy that collects them and if they are in high grades will pay more for them but not much....I think the most I saw one got for was in a ANACS slab and was in the higher MS60's and it went for $15...I'm sure some have gone higher but most I've seen go lower.

I used to drop a quick "nope" until someone found a california quarter with a few letters missing and threw it up on ebay......went for $15+....proved me wrong. To error collectors it has a bit of a premium. For "perfection" collectors, its worth $0.25
There's something else to remember too - not everybody buying coins on ebay knows what they are doing or the true value of the coins they are buying. Every 5 seconds or so somebody is paying too much for something on ebay. Find 15 or 20, or more, of the same item sold on ebay - average sale price - then you'll have a better idea of actual value.
