Over the years I have come to the conclusion that the cheap option is to buy coins from sales where the consignor should have known better than put the thing in that sale. In the case of a Triton sale, that would be a less-than-the-best coin. The definition of junker still can involve a lot of money. If you are bored, look at the prices realized on Triton XX and you can find coins that would fit better in my collection than in that of a billionaire and several went for the start bid. A few did not sell. There were bargains but not the coins that drew a lot of attention. Find the lots the big dogs don't want. This sold for the opening bid of $1800: https://www.cngcoins.com/Coin.aspx?CoinID=324342 I've seen better but this is nicely centered and would fit my collection. In 1989 I was a bidder in sales run by Numismatics Fine Arts where the same specimen sold for $1400 on an estimate of $1800. That is not a lot of change over 28 years but Triton XX included two nicer Archaic owls (the best went for $13k) and people with thousands to spend don't go for bargains. Sometimes you either have to figure there is never any point in looking for sense in this game. In Triton V the coin below was estimated at $40k. I do not know if it sold. In XX if was estimated at $10k and brought the opening $6k. At this rate I might afford it next time. https://www.cngcoins.com/Coin.aspx?CoinID=324859 There are always new finds (more and better coins or opinions that all the things are fake) but the 2002 NYIC to 2017 NYIC performance suggests that there is a lot of fun to be had reading prices realized.
