I came across a interesting post on internet, folks I would like your expert opinion. http://www.coincommunity.com/forum/topic.asp?ARCHIVE=true&TOPIC_ID=32431 take a look at coin image posted by gnome - 07/02/2008 10:43 pm, do you see a slight crack? I have a similar crown and have noted identical crack at the same place . I purchased my coin from UK , ebay from a reputed dealer checked weight around 28 gms, dimensions perfect markings , but just this slight crack
