Of course it is just an opinion but, I see the red mini #/5 @ 10,000.00 black mini @ 1500.00 brooklyn back 2500-3,000. printing plate 25,000.00 the common mini @100.00 . Any 1/1's will be super expensive like the blank back from the topps vault.
I put a value on my other five favorite inserts @ 10% to 15% of the crypto card. The recent samesong park red mini went for 230.00 and the crypto red mini went for 2700.00 as an example of value comparison. If a red mini solar eclipse comes up for sale right now I think it will take 275.00 minimum to get it and maybe more.
I often look at the pick your card sellers on ebay like the ginter black mini to see if they have one of my favorites and they are always sold out. Gives me a good indication of the popularity. This ginter x because it is so limited will always be a favorite and supply and demand is always in play It isn't just the crypto collector but, also the mainstream card collector that collects these.
I have no experience with cards, but i'm bullish now that i see other cards start to increase in value. I notice that graded cards seem to go for double of non-graded cards, so when PSA starts to release the cards they are holding - watch out!
