Are you asking about the H-Mold, H<>C with the number under it? $3-4 Harold's Club? Or the Lg-Key "Reno Horseshoe" with the horseshoe logo inside? Same goes, I've seen them around for less, but TCR lists them at $10-14 Sm-key, $15-19...

Hope one of those is the one you are asking about there are more.

Or maybe can you be more specific?
