What about you - can you boast something rare too?

countries from which I got only one postcard - during my 10 years on postcrossing:
AX-3614
AM-6799
CY-2363
ET-1101
IL-14424
KG-463
XA-222
MK-2179
PA-332
PR-2815
TT-5888
TN-3154
TV-274
There also was a card from Iran sent via Germany but Paulo removed it from the system because the Iranian user was afraid to show any relation to Israel, even such a small one. Also I got 2 postcards from Iceland and 2 from Guernsey which are pretty rare countries too. And 3 from Macao and Kazakhstan :)
