Looks like a 1 MB board to me. The DAT board is over the CPU, and two memory chip boards each with 512K where the RAM is.

Also, how many wires are connected to the memory board from the DAT board that contains the 6809 cpu? If there are two wires labeled D6 & D7, then I would expect you have a 2MB Coco 3! :) Just one wire labeled D6 would definitely be a 1MB memory upgrade. Try running NitrOS-9 on it and let us know what the mfree command displays. Inquiring minds want to know! :)
