8 Cent Ike Mint 1394 Partial Misperferated Sheet

8 Cent Ike Mint 1394 Partial Misperferated Sheet. Not a stamp person but came across this the other day. Nice fresh original full gum. Hard to imagine some one missed the error and used them. Found singles online for 2- $20 each and I think a plate or other block of 4 for around $20. Did not see anything with more than that many stamps still intact.
