My lowest postcard received was from MACAO 
on 19 April 2010. Back then I even didn’t know such a country existed! 
Love learning new things through postcards.

My lowest is GG-3759 (sorry no photo at present) from Guernsey. This arrived in 2015, I’ve been Postcrossing since 2011.
I have a new lowest postcard that I received but it’s still not that low.

Haha! Such impressive numbers. My lowest is ES-709334. It is lower than all the cards I’ve sent from the US even though it is one of my most recent.
My lowest received is RO-188822!
