Celluloid presentation ring case velvet double heart & wedding rings set 1950s

In good vintage condition this is the case and silver engagement and wedding ring . We estimate by family ownership the case is a few years older than the ring set .both have been stored away for 40 yrs plus . No idea the value of the rings since if they were marked it is gone though I'm told it wasn't mandatory to mark them in the 50s so some jewelers did not routinely do so. The rings are in excellent condition the metal and stones are secure and clear . My camera cannot pick up the brilliance or fine details like the hearts engraved in the ring setting. We value the case by comparison to many other postings for like cases at $45 and the rings since we can only guess by the same at $75 if the metal is silver tone . And if better we take that loss , totaling approx $125 But for a quick needed sale to help repair my car I'm asking only $99! ON Bottom of caSe says W&S NY PATENT APPLIED FOR
