Without the velvet lined coffin (LE50 - given to the 1st 50 attendees at the Halloween party in 1999) its worth about $10.
Last one of these on ebay fetched $300+.
This one will be on sale shortly amongst 900 pins from 2 fine collections. It will be a fraction of that price
If you havnt already done so, email me if you want to go on the mailing list for the catalog. Should be finished within another week.
