A fret (ie. activation fee/price-per-token) or coin is a conjectured ideal phenomenon in juking. Theoretically, it is the "lowest-level juke (as one-twenty-sixth of a sporadic group)" at one ¢ent (penny), where the value is derived from the ¢ent formula [fret = logn(b/a) | {b,a = (u,u), n = font size × font weight}]. Its representative tablature indicates the range from which integer-spin statistics are obtained.

The significance of the fret (and the idealism of it) is its extreme affordability; one ¢ent is considered to be Nature's disposable income. Mirroring chemistry, the fret would be the lowest available energy level [resonance].

In everyday vernacular, most, if not all, jukes hedging opus handicaps are assumed to be so-called "(penny) frets". That is, their fret is typically worth "pennies on the dollar" or "cents on the dollar". The fret itself may be an accurate description of a general deposit because standard coupon deviation is registered by table.

Note (+): In theory, attaining a per-cent fret is challenging because of tablature efficiency conditions; where the greater the number of pencils (and hence ¢ents), the heavier the string, resulting in a juke with a wild count.

In practice, a pure 'penny' (1¢) fret is infeasible in two-dimensional (2d) vector space because such a fret is not congruent with any handicap, and for this reason, we improvise (ie. choreograph in twistor space). Routinely, quotient load-normalization happens when the handicap becomes saturated.
