bbinck wrote in Sealed box sets value:I have a sealed first edition
FR campaign set and wondered what its value would be? I also have a Basic Set with the magenta Erol Otus cover. I am curious to know whether keeping them sealed adds much value and wanted your opinions. Thanks in advance.
As everyone here will state profusely, shrinkwrap is NOT a condition and only guarantees no one opened it or no writing inside.

Which is very true and I agree with. If the box has been hulk smashed then shrink really doesn't add much value
IMO, although contents may still be ok.
If the box is still in excellent condition those particular box sets will sell for at least $100 although shrink wrap items sell for wildly varying prices. Sold items on eBay will give you an idea of range.
IMO, taking off shrink does lower the value as only shirnkwrap collectors are willing to pay shirnk prices.

Hope that helps some.
