I kid you not!!!! We had the very same hamper growing up!!!!!! However, our wooden bottom ended up busting thru - we kids would use it as one of our hiding places playing hide-n-seek! LOLOL Great memories!
Now the inside of ours did not have that coating - just wicker. So either it was a "step up" or someone coated it. I can't say as I have seen any of them have that inside. Smart tho for the snag factor - but probably not so good for the bacteria/dirt factor.
In pristine condition would sell between $30 - $50 in my neck of the woods.
