I don't own this chip. Do you? If you do, is this one chip with two different sides, or is this two different chips?

I ask because I always thought it was a single chip, but while adding this submission to NevadaOnes.com I was looking it up in The Chip Rack and it appears to be listed as two chips, E2371 and V9635.

BTW, if anyone has a nice one of these for sale or trade, I would like to get one or both depending what the answer to my question is.
