  1. This, for the sesquicentennial, would be the fourth.

     

    While the US has yet to issue a commemorative note, it has issued notes and coins of new types on significant anniversaries e.g. 1909 Lincoln cent - birth centennial, 1932 Washington quarter - birth bicentennial, 1976 $2 note - Declaration of Independence bicentennial.

  2. Are you referring to gross weight perhaps? The ASW of the core part should be 0.6 ozt for the older ones and 0.5 ozt for the newer ones if I remember correctly.

     

    The ones with .999 marked on the outer brass ring rather than on the actual silver part inside are usually older issues - I'm sure someone got warned about the legalities of stamping such a marking on brass.

  3. I remember reading somewhere about certain newer coins being slightly underweight so they align with older ones in circulation, but I'm not sure if that was in reference to US quarters. (Historically, it has happened in China, where the "Fat Man" dollars of 1914-1920s were made to match the ASW of a average circulated dragon type dollar.)

     

    I agree at ATB quarters have a different shine to them, though I usually recognize them by the different obverse which is a bit modified from that of the state quarters. I wonder if there might be something going on with the height of the rim maybe? (just to throw something out there)
