this year i hope to complete all Bangladeshi coins by type and date. some of the dates are very very hard to find. mostly unc, least will be xf.
just asking, what is important thing to do to be a numista country referee.
for example i want to be a country referee for bangladesh. i want to add all info about date, edge, minor varieties etc. error are expensive like 1000-2000 taka or 15-20 USD. but still if necessary, i will find them for info purpose.
