I bought these 2 strikes from a former Palms cage worker when I was in Vegas mid February to help my son buy a car. The lady I bought them from had a very extensive Palms chip collection and just these 2 strikes that she had listed for sale on Facebook. She said that there were a total of 5 strikes that were split between her and a co-worker. These 2 are Sorcelita and Slither, which makes me believe that the other 3 were Desmonda, Frankenstina, and Shiver, which would have made a complete set of full frosted prototype 2005 Halloween Palms Strikes, as the full frosted Draculina is already known. She knew anything you wanted to know about Palms chips, but didn't know anything about the strikes, but thought there was something special with these. She said she would try and contact the co-worker that got the other 3 to see if they were for sale, or at least get me pictures and let me know. I am planning on listing these on Ebay within the next week. There is some toning on the Slither rim, and some light toning on the silver near the rim on both strikes. Even though I no longer collect strikes, I still keep my eye out for them. I will post any info on the others if I get any.
