I agree with Kurt, contrast will help. I would also suggest using a scanner at least 600 dpi.
For price, based on the 1968 dollar doubling variety particularly the REGINA and beads like your coin (ref. p519 Charlton Std Cat 60th) your coin could be valued at $2. A certified MS-63 could fetch $20, provided the doubling is apparent without magnification.
But valuation is extremely subjective when it comes to those types of varieties...
