Price Check for sequential Colts?

[red454]

I have two brand new in the box / never fired Colt 70 Series Repros (O1970A1CS), each with the 100 year roll mark. Long story but I ended up with two of them from two different vendors and somehow I ended up with sequential serial numbers. Anyway just trying to get an idea of what a pair of these would go for since I haven't seen this combo on the auction sites....If anyone has an idea I'd appreciate it.
