I wouldn't pay any more than $15-$20.These Ebay sellers asking $50 must be high on meth.
They try and take advantage of the people who don't take the time to do a little bit of research before diving in.
I would think if you are patient, a nice, rolled copy will open at 9.99 or less and you win.Happens all the time.
If they pay a penie or two pence more for the reddinesse of them..let them looke to that, a foole and his money is soone parted.
