can you tell me if these have the private key on them? These are an actual bitcoin ? Or is this just a silver coin?
This physical coins are Casascius. They have the private key inside the rear sticker with bitcoins. A and B have 1 BTC and C has 0.5 BTC.
You can check the bitcoins are untouched searching the Firstbits on this website:
