The value in a push-up player attachment that has the 88 fingers
would depend on what you think it's worth.  I have only heard of three
of those units in my years of collecting.  They have large striking
pneumatics but they play great.  I would guess most people today would
put a low price on one of those units.   The only one I have seen for
sale was priced at $2500, unrestored, about 15 years ago.

Today's market is all over the place, depending on who you talk with,
but the figures just came out in a trade magazine showing that piano
sales in 2010 were dismal.
