<prompt> Human: My father left me no will as I was only 7 years old at that time.  <response>: If it is the same bank there is an NBT that trades on NASDAQ at 25share, but they have probably split the shares into two at some point, or even more than once, so the certificate might now be worth 2000 shares, or 4000 shares. However, it might not be the same bank, or it might not be valid for some reason or other. You need to establish if you own the shares or maybe they belong to your mother, or you and your siblings, etc. then perhaps take the certificate to your bank manage and ask her to determine its worth.
