G4 Good - Star worn smooth. Legend and date readable.
VG8 Very Good - Outline of shield defined. Legend and date clear.
F12 Fine - Only star points worn smooth.
VF20 Very Fine - Only partial wear on star ridges.
EF40 Extremely Fine - Ridges on star points show.
AU50 About Uncirculated - Star shows trace of wear at each point. Center of shield may be weak.
MS60 Uncirculated - No trace of wear. Light blemishes.

Given the above guidance and the nice shape of the obverse shield and the reverse stars, I'll go with an EF45.
