I read the OP and skipped right down to the bottom without reading the other posts, but from my experience is that these rolls are purposely made to have 2 coins of value on the end and they use "New Old Stock" wrappers to make the rolls look legit. Of course we've all thought of buying a roll and trying our luck and that is what you did, which is OK, whatever makes you happy is all that matters.
Anyway, in this hobby of CRH we also know how rare an ender is let alone an ender of value, and what are the odds of getting 2 enders of value and one of them being a mercury dime, roosevelt dime, barber dime, etc? slim to none. I have found 1 dime in the last 1000+ penny rolls i have gone through from the bank and it wasn't an ender and it was not silver.
Please don't take this post as an insult, it is not intended to be so, but as long as you're happy with the roll that is what matters

HH and good luck,
