Can anyone tell me much this chemise is worth?

I was donné this chemise to sell on e-bay but can't find any info on it on the web. It was purchased in 1994 in a FL boutique for $450. Printed with comic strips from 1992 & 93, Charles M Shulz logo & united features syndicate 92 and 93. Manufactured par Iceberg Italy, it's a Mens Large button down dress shirt. Never worn. He told me limited edition - only 10 of these shirts manufactured but need confirmation before listing it on e-bay.Not sure what it would be worth to a collector ou what I should put as a starting bid. Would appreciate any feedback ou conseil from someone who might know. I have several plus photos with close-ups on an online album at:
