They seem pretty elusive like the snow leopard
It took me over a decade to acquire Beni Chidori (and Seigen) parent plants. To my knowledge, I am the only person in North America propagating them on a large scale (+1000 per year). I have been steadily supplying professionals, garden centres, bonsai nurseries, and hobbyists since 2020. From what I have seen, a small percentage (about 250-500 units) are purchased from me for re-sale. However, it's likely that buyers are selling/distributing to their waitlists and friends lists and that therefore the material is not being listed publicly by them. I don't know, I don't ask.
If you give it another 5-6 years, the price should come down to somewhere around the price of other cultivars like Deshojo. Of course, and to answer your question another way, even the price of Deshojo varies greatly, I'd say from $10 to $150 for young material depending on the quality of what you're buying and the time and resources that went into caring for it during its initial stages.
Or if you have seen others priced at any aged, I'd be curious to know?
Once you get to a certain level of quality, a good japanese maple is a good japanese maple, and cultivar barely affects price (there are a few exceptions to this, such as shishigashira or arakawa). I have seen prices for Beni Chidori vary from $50 to $50,000, depending on the quality (not the cultivar).
