Garden Flower RM2 - 2010/1

I just acquired the serial number block for RM2 garden flower definitive stamp. The serial number is 2010/1 (click here to see serial numbers for denominations 60s, 70s, 80s and 90s, and click here to see serial number for denomination 30s). So, now I'm still hunting serial numbers for 50s and RM1 denominations.
