Proof like, worth the premium or not, adams edge lettering error

I'm a big presidential dollar error collector. I've been offered a John Adams double lettering edge proof like error (ngc ms65) for $250. Typically, ngc adams double lettering edge errors in 65 grade go for around $75. The seller claims he has never seen a proof like in the adams double lettering edge errors and neither have I. Unfortunately, there is no breakdown in the ngc or pcgs pop reports on the amount of proof like errors that have been graded. Does it seem like it is worth the $180 premium to pay for the proof like coin and label?

Just want to make sure that it's not a partial descrition
for "planchet"......
If it is a 65PL, I'd say it's probably a good shot to take.
I've never seen a PL surface on on any MEL or
doubled edge lettering error dollar....

This time I was.
I got to eat me words.
I guess I have't seen enough MS nor SP sets, as some have come back PL and DMPL.
I'm with Fred, and to some extent a bit of what I said.
And if it really has a PL or DMPL designation on the label, then maybe consider it.
What I said that I'll stick with is that I'd want to see it in hand, or at least see a shot of the coin and label showing the designation.
