Impossible to tell from your photo though which one you have and what, if any, the inscription says. If it has the paradise logo under the clear plastic ring (if yours has a clear ring), you can add a few hundred.
Ivory joints can increase the value by a few hundred dollars also.
Having an two shafts as you do certainly helps with resale. Two shafts were standard for Frank Paradise cues, so if you only had the one shaft, you would deduct value. If any of your shafts are no longer straight, you also deduct $200 - $300 from the value.
If the cue has the original wrap, finish, ferrules, and shafts (e.g. nothing replaced or refinished) you can add 20% to 30% to the value.
Some for more famous players or more well-known players and those with a certified provenance can go for $2000 to $4000 and up.
Some special Frank Paradise cues (e.g. like those made for ultra-famous people) can go for upwards of $25,000 e.g. the Frank Paradise cue made specifically for Willie Mosconi to give to Mickey Mantle:
