Not the best quality picture, but it shows Types 1-3 (from left to right), as described by Mark Laukner.

All three in this picture all fall under the [060] embossing index in the price guide.

Type 1 is probably the most common profile and can be found with many other embossings.

Type 2 is (I believe) only ever found with the [060] embossing.

Type 3 is also found with the [160] embossing.

Type 4 [id=133280225] is the "3 1/2" tall; modern style" [165] and is easy to distinguish from the other styles - it is mostly found in straw/peach shades and a hard to find light green.
