Two better registered covers sent to Australia in 2000 and 2011 and both franked with better security Machins with elliptical perfs. The 2000 cover has a 3 GBP engraved with a damaged corner. The second cover is franked with 12 1st gold stamps with MTIL source code and MA10 year code. The stamps off cover catalogue a total 42 GBP, so at $20 the covers should be well worth our estimate.
