In my experience, the best way I’ve found to differentiate between the FS DDO-001 and this DDO-001 is the little dangling fingers from the top of the G. The non-FS variety, this one, tends to have a much longer finger further to the right of the top nub of the G while the FS DDO-001 may have two little bumps more towards the middle that protrude much less. I’ve tried using the protrusion off of the second T in TRUST but sometimes I’ve been fooled by different die states/proof doubling that cuts off a little bit of it. This is my go-to method now!
