Definitely not. It has four initials. You'll have no clue it's from the mint besides for the weight.
Very true about the weight - it's a shame you can't have it delivered straight to the bank!
Strangely enough, it costs the mint a bundle in overnight shipping charges & credit card fees, and then the bank has to pay $$ to send it back to the mint! One time when I shlepped in $4,000 in coins, the teller at Chase asked me if I had any more! I meekly replied that I do, and then he asked me to bring in the rest of my stash ($11,000)- so they will only have to pay once for shipping - crazy!
