Feedsack Value??

Hi Ladies,
In cleaning out my mother's basement last week, we found 19 intact feedsacks.  Five are prints and 9 are heavier muslin.  None have any holes --other than where the seams were.  Most are clean and ready to use.  A few have some stains that I am working to remove.

My question to any/all of you is what kind of value do they have?  I would like to list them on ebay or a quilt list, but don't know what they are selling for.   I have seen them in antique stores several years ago for $12 each and those were small pieces.   It looks like they may be going for about $5 a piece on ebay.   I welcome your input.

Thanks!!
