Without a good look, $7

Two obverse varieties, circulated $15-25 depending on wear and type
1942 Tombac Nickel88% copper, 12% zinc 4.54 grams 21.3 mm
Mintage 3,396,234
Just a guess at $1.50 x 2
I went the conservative route on my estimates as the
pictures are small and I can't tell varieties or grade
very well. Worth $50, a coin shop owner may offer half
that. I just paid $7 for a worn 1912 Nfld 20 Cent piece.
