New challenge -- - Post your coin with the highest KM#
==========================================
1) Limited to coins in the Krause Catalog (generally after 1600. with some back to around 1500)
2) Coins mist have normal KM# NNN -- not X# (unusual coins) Y#, MB# etc.
3) Must not have KM# TnNNN (tokens), KM# ENNN (essais), KM# Pnnn (piedforts), KM# PnNNN (pattern), KM# PrNNN (provas/probas), KM# MSNNN (mint set), KM# PSnnnn (proof set), KM# SSnnn (special sets), KM# PLnnn (proof-like set) KM# TsNNN (trial strike) numbers, or any other special number.
4) For numbers like KM# 123.1, KM# 123A, KM# 123.7a etc -- only use the part before the . or a, etc.
5) For numbers like A201, A201b, just use the numeric part.
6) New coins not yet in Krause and older coins not in the catalog don't count, and will get 0 points.
7) The number of points awarded is numerically equal to the KM# -- see (4) (5) and (6), above.
8) In case of a points tie, the earliest post wins. If one user posts multiple coins, the one with the highest KM# is used.
9) Posts with no coin will get 0 points, but will appear in the leaderboard. If there are no valid posts, the first post with 0 points wins this round.
10) Please include the KM# in the post.
11) There are no bonus points for an exact match.
12) Added: This round ends June 2, 2019 at 21:30 forum time (EDT).
If you don't have acess to a Krause Catalog, the online Numista catalog often gives the KM#, for modern coins.
