Help identify?

[wpd7]

Looks like greasers, but anyone in the know can help?

One is a 77D stamped on a proof planchet? Trust is missing letters as well as some of the stars in the background.

One seems like a huge greaser- almost nothing but the kennedy bust.

Also, can someone elaborate on the key dates of the Kennedy halves? I was told 78P/D, 86P, 93P. Is there any values to these? Sites on the web point to anywhere from 58c to $7 for circulated conditions.

Lthink it was cleaned, but is not a proof planchet. NOt quite the right shininess, and the frosting is not there. I've had some that were VERY shiny, but that is not the same shine as the mirror like shine on a proof.

Just my opinion, which is worth less than the coin in question. :-)
