I used to sell this set in PF69 for $6000-$6500 in 2011, but then Stacks dumped hoards of these coins and today a PF69 set is around $3500.

Since you have some PF70s the price is a little harder to come with and most likely the coins sold individually will be worth more than sold as a set, since most collectors don't want mixed grade set or they like to build PF70 set on their own for a sense of accomplishment. The key PF70 (see pop report below) are horse, dog, rat and pig. You have the pig, so add roughly $500, all the other PF70 common (supply exceeds the number of PF70 collectors) so add roughly $200/each x 6 = $1200, the horse is PF68 deduct $200, total I would estimate $5000. If you have the COAs and boxes, add $200.
