RG handgun quality varies from abysmal to okay - depending on the model. But, they all share one thing - no real value. They have no collector interest and are considered of poor quality overall.
If you worry about safety with children in the house, I would suggest turning it in on a city 'gun buy-back' program for whatever they are giving in exchange - money, gift cards, etc. Or turn it in to the local PD and let them dispose of it. You would be very lucky to get anything for it from a gun/pawn shop - they just don't command any value.
