Can this leather be used as a strop?

I got these two pieces of leather from a friend, the only thing I know for certain is that it is 100% cow hide. If I scrub these with a leather conditioner/soap and do a very light sand to get rid of the shiny surface, can I use this for a strop? Thanks

looks good to me.

You could lay the one on the left beside my strop and think they came from the same cow. Nearly identical..
