I have taken a photo of the key but photographer Im not. I hope its good enough to get the details from.
Clearly, its a Schlage key. If I could see the profile of the blade, I could tell you the keyway, but it is better that you not put photos of your working keys on the internet.
Generally speaking, if a Schlage key does not have a letter (like C or E) or tiny numbers (123) in the corner, then it is SC1. That's the standard default and doesn't need to be marked. There are exceptions... but I think in this case it is safe to assume you have SC1. Which character will you be getting?
