Terrible value for money, sorry. Best card you could hit would be a Treloar Finest or Cotchin guernsey sig- probably sell either for $500-600. You are a 1:9 chance of hitting either and i don’t think I’ve ever seen a case with both.
There is very little interest in the Team Leaders inserts (3 per box) - check out eBay and you’ll see the majority sell for $10 or less and even the big clubs/players won’t fetch more than $25-30.
I know 2017 Certified is sold out but it was far better value with the inclusion of one Influential per case. Many of these are now worth $500+ and the top few in Adams, Cripps, Hodge would sell for $750+ these days.
Plus the list of guernsey sig cards was better for 2017 series - Pendlebury, Naitanui, Gunston etc.
