As noted, you have 2 completely different frames that happen to have the same name/color, so the idea of selling one, as-if you have duplicates simply doesn't apply.
Obviously you can afford both or else you wouldn't have both.
Selling either without even riding either , what would be the point of that ?
Why did you even buy either ?
...... you fill in the blank.
Seems to me the only proposal is "which bike am I riding today ?".
