ah dont know about nikons closeup filters. from what I remember they didnt make 77mm sizes back then. not sure today. today cheap ones that are decent can be had for $15 or so for 3 strengths. the ones you posted with the contacts are plastic body with metal mount. thats ok. the problem is mounted lenses with more than 1 tube and there is a flex and you can even see the lens has a slight bend downwards. and it will havesome slight movement. contacts are iffy. they mostly worked but sometimes they needed to be removed and remounted. I didnt want to deal with that and bought the all metal ones for peace of mind not in reliabilty for fear it would break but because of the flex/wobble thats annoying for critical work.
