Hi,   
I am new to the forum. I am not really a train buff.  My father however worked for Lionel Trains many years ago.
 I have 3 employee service pins he was awarded during his time there.
  A 10 year, a 15 year and a 20 year.
I can find little information on them.
Anyone know if they are collectable and what their value might be ?

Thanks for your reply. I found an auction site that listed some sold at auction, some sold for close to $500.
I located a collector who owns a train store. He bought all three for a good price.
I too though they would be a nice heirloom.  I have 3 grown sons who had no interest in them as such.
