In fact the equation is easy to solve. Are old NBTHK papers still valid? According to NBTHK itself, no. So these old papers are nothing more than TP. If people don’t want to send their blades to Japan for new papers, they can submit them to NTHK shinsa.
Nobody right in his mind is going to pay any amount of hard earned cash on an invalid certificate furthermore 34 K$.
In other word, at the opposite of what is often said, you buy the paper (at the lowest level i.e. Hozon) for the guarantee you are not going to be cheated and pay the right price, meaning the one you are ready to pay for the real thing.
In Japan, this blade will be considered non certified and nobody would buy it at this price.
There are certainly old papers valid but nowadays they are obsolete, we are in the 21st Century.
The « buy the sword and not the paper » only means that you are willing to buy uncertified blades at uncertified prices, because noone is going to take the gamble when several k$ are at stake
