BeCu Pal 2 putter

A buddy of mine told me that Ping released a limited version of the PAL 2 BeCu putter. He said they would be numbered, milled, and a line inside the face (maybe meant cavity?). Anyway, I told him I scoured the internet and eBay for those models he referred to and I didn’t find anything. He suggested to try this sub. Here is my model of the PAL 2 BeCu. Anyone know the value?
