I wasn't familiar with these skulls until I did some research on the web. Apparently, Randotti-style skulls and headstones were sold in Disneyland as souvenirs for the Haunted Mansion in the late 1960s and early 1970s. Haunted Mansion items are very popular, but I don't know the current value of your skull. I would expect that yours would tend to sell a bit below the average price (whatever that is) because of the condition. In situations like this, I usually recommend that you create a "Saved Search" on eBay so that you get notified by Email when someone offers a similar item for sale. I'd just use "Haunted Mansion skull" because the name Randotti may not appear in all of the auctions that might be helpful. Good luck!
