I think I need a tool
went to the local bank window yesterday and got a bunch of dollar coins
(US) and gave em a quick look over, To my Surprise I pulled a proof SBA and a Andrew Johnson that needs a much closer look. That be the one I need a micrometer to measure the diameter. No Edge lettering evident even under 4X sheep magnifying glass. (forgot where my stronger lens are, will have to hunt those also) |

These 6" digital calipers also can be had from many vendors for less than $20. http://www.harborfreight.com/?utm_me... hoursale_1053 (Scroll down the page.) I also have two digital scales ($20 - $30) and several magnifiers in 4X, 7X, 10X+20X each bought on-line for less than $10. |

At the very least, it's virtually impossible to hand-file or abrade that much of the edge and maintain perfect circularity. You'd see the irregularities even without a magnifier. But the simplest method is to stack a suspect coin on top of an unaltered one. After removing that much material, the difference in the diameters should be obvious. What were the indications that these were proof versions? One obvious marker for proof Presidentials is an artifact of the way that the edge lettering is applied. Instead of running them through an edge roller, the lettering is impressed using a 3-part collar that is squeezed onto the edge. This leaves three distinctive vertical bars at the 10, 2, and 6 o'clock positions marking the junction points of the three collar parts. |

At the risk of using a word that will surely attract el Reamo, Prezibucks may be homogenous. oly |

I'm just reluctant to ruin a coin, even a common business strike, for the sake of empirical testing. |

The Andrew Johnson $1 US dollar I have has a VERY weak strike on the rim, a little bit of it visible with enough magnification, but there is some of it there. |
