Dearborn: Basically is a half grade - PCGS uses a + so NGC cannot and went with a * so that grade is PF67.5
The "+" is used both by NGC and PCGS, and was introduced at the same time by both companies in May 2010 (some nearly 14 years ago).
Citation here on PCGS website. The "
+" is a grade modifier that means that the coin is
high end for the assigned numerical grade. In other words, something like a half grade.

triggersmob: I'm curious as to what the * means after PF67?
The

is a modifier used on labels only at NGC. It was introduced long before the "+" was introduced, and there is no equivalent designation used by PCGS. It does
NOT indicate anything about where the coin falls within the numerical grade assigned (e.g., an MS64

coin does
NOT mean that it is at the high end of the MS64 numeric grade, i.e., "64.5").
Instead, the

means that a coin has exceptional eye-appeal (see the complete description
in the link that was already provided).
Functionally, the
is assigned to non-proof coins somewhat differently from how it is assigned to proof coins.
For
non-proof coins, the

is assigned because a coin has very high eye-appeal. This usually means that the coin has booming luster, exceptional strike, or (in most cases) some very attractive toning.

For
proof coins, the

is assigned because a coin has very high eye-appeal, but the

is also used to indicate a coin that has CAMEO or ULTRA (DEEP) CAMEO contrast, but only on one side of the coin. A proof coin can receive the

because of toning, but the

is
usually applied to proof coins because they have CAMEO contrast on one side or CAMEO contrast that is appealing but does not quite attain the required standards for the official CAMEO designation.
The 1959 PF67
Roosevelt dime posted by
Marve65 is almost assuredly given the

because it
almost reaches the requirements for CAMEO designation (not because of any toning).
