 Back in 2003 I bought a set of NEW Titleist 680 forged blades with TT S300 shafts from Golfsmith. I know that there have been MANY questions in the forum about authenticating clubs, and where to find the serial numbers.

&lt;p&gt;Custom set serial number on all irons.&lt;/p&gt;
&lt;p&gt;I think having a serial number on all irons would be a good idea, it would identify all the clubs as being yours.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>Re: Titleist 680 Authentication</title><link>https://www.titleist.com/teamtitleist/thread/37434?ContentTypeID=1</link><pubDate>Sun, 05 Jun 2011 01:10:46 GMT</pubDate><guid isPermaLink="false">9ab519fc-5311-4952-85cd-0a0ceffb73fb:a190fc2c-b7c9-424e-a183-8321c2640182</guid><dc:creator>Jason S</dc:creator><description>&lt;p&gt;Trey,&lt;/p&gt;
&lt;p&gt;Check with Cathi or Nick, but it is my understanding that if the set is non-custom, then they will only inscribe the serial number on one club, ususally the 6 iron.&amp;nbsp; It sounds like this is the case with your set as the 680&amp;#39;s came standard with S-300 shafts.&amp;nbsp; I own a custom set of 690MB&amp;#39;s and 710MB&amp;#39;s with the serail number on all of the irons as they are a custom set.&amp;nbsp; &lt;/p&gt;
&lt;p&gt;Now, if you order a custom set (i.e. order the set with a non standard shaft shuch as the X100, or order a longer than standard shaft, custom lofts, lie, etc.) then Titleist will inscribe the serial numbers on the back of the hosel on all clubs in the set.&lt;/p&gt;
&lt;p&gt;Based on your description, I am&amp;nbsp;almost sure that your irons are authentic.&lt;/p&gt;
&lt;p&gt;Thanks!&lt;/p&gt;
