Submitting British - To cross or not?

I'm going to send in my 1/2 d restrike and need to fill out the submission. These are all Anacs slabbed from the late 80's and early 90's. What is your opinion. I am cutting back on most of my circulated British but I'm planning on keeping these for a while because they both look so good.
Are they worth crossing or not and should I crack them out first?
Common 1787 with Hearts Shilling, currently Anacs AU55:


I tell you, the fields look 63+, just a weak strike or a little cabinet friction on the high points of the hair.
1758 Shilling Anacs AU55:


Clashed dies are obvious ont he obverse and revers, but otherwise the fields are very clean, weak at the highpoints of the hair and on the shield devices.

Certainly they should be worthy of crossover if you felt the desire to get them in more modern, higher-tier plastic.
I usually crack out before resubmission, but that always has the downside risk of a bodybag or unwanted grade if your new TPG isn't in a friendly mood. If you submit for crossover in your old holders, you might risk bias, but there's less potential downside, since if it doesn't cross you'll still have the original holder. I believe most services let you state a minimum crossover grade.
Nothin' wrong with old ANACS, though, as far as I'm concerned. Why bother, unless you really want different plastic.
edited to add: I would submit the restrike without question
