[QUOTE="-jeffB, post: 3250845, member: 27832"]I [URL='https://archive.org/details/annualreportofdi1902unit/page/n5']found the report in The Internet Archive[/URL] (and made a donation). It'll take me a while to get through it. I would've expected higher losses on halves than dollars, for several reasons: 1) Among heavily-worn coins from that era [I]I've[/I] weighed (dimes, quarters, halves, dollars), the smaller denominations had lost proportionally more weight. 2) Losses due to surface abrasion should be proportional to surface area, other things being equal. Relative surface area is greater for small coins, less for large coins (square-cube law). So smaller coins should lose weight faster, proportionally. 3) From all reports I've seen, dollar coins never circulated as heavily as halves, quarters, or dimes. So, I'd like to see if there's additional context in the report, so I can figure out which of my assumptions are off-base.[/QUOTE]
