hey man , Listen care fully this offer came to me 3 months ago then I started looking for it all around and i found more than 200 coins of 1978 & 1980 with both dot , stars and diamonds one . All of them where 7.5-8 gm . Then I got confused that if from more than 200 coin I could not get a single one that showed more than 8 gm ... then i went to search about the weight of these coins and You know what , I found more than 10 sites which claimed that those coins where minted at 8 gms only .... So it does not worth searching 1978 & 1980 weighing 8+ gms... And if any one claims then he is trying to do cutting
