<p>[QUOTE=&quot;koala, post: 1313150, member: 34595&quot;]Hi all</p><p><br /></p><p>&nbsp; I am opening my collection to platinum coins for the first time. I&nbsp; bought a Australian Platinum Koala 1/10 oz, year is 1990. </p><p>I checked its&nbsp; measures to evaluate the content. It turns out to be 3.16 grams,&nbsp; diameter 16.04 mm, thickness 1.11 mm.</p><p><br /></p><p>&nbsp; The last parameter puts me a little off. <a href="http://bullion.nwtmint.com/platinum_koala.php" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://bullion.nwtmint.com/platinum_koala.php" rel="nofollow">According to specs</a>,&nbsp; the coin should have a thickness of 1.40 mm. I never had a coin so off&nbsp; in thickness, although technically the density is higher, and platinum&nbsp; has the highest density among normal metals, so I can&#039;t see how it can&nbsp; be counterfeited. Can anyone with the same coin confirm the measures of&nbsp; thickness, or eventually explain where the problem is ? Will I have&nbsp; problems reselling it with such difference ?</p><p><br /></p><p><br /></p><p>&nbsp; Thanks[/QUOTE]</p><p><br /></p>
