I would say no. Some here have tried to buy $1000 bags of Ikes and often times they arrive with less than $1000 worth of Ikes in the bag. You might get lucky and score an Ike that is 40% silver (worth about $4.29 at today's price based on silver content; less than what a 90% half is worth based on silver content).
One or two ultra lucky posters have mentioned obtaining a couple of old silver dollars (Peace or Morgan) in their $1000 Ike bags, but most who post here and buy such bags do not get such trophies.
To buy them above face value on ebay is crazy, unless you just want to build an Ike collection and can get a year you otherwise cannot obtain.
I was buying Ikes from banks for a while (bought a few hundred or so), and never got anything special regarding the dates.
