General Market Notes
Excluding proofs and errors, the key to the series is the 1899-M issue and the semi-key is the 1905-C issue.
Krause catalog information may conflict with the diameter & weight shown here. This site has measured and weighed 16 different coins from both mints and all coins measure 20mm & 3 grams. The Krause catalog goes further by assigning two different catalog numbers (KM# 394 and KM# 394.1) for the series implying that there are distinct varieties but the only difference between the two are their mint marks.
