Actually, I sorta wonder now why the perfect bid bonus hasn't increased to $1,000 with you saying that.
Most of the cash bonuses and games have lagged behind inflation. The perfect bid bonus is actually not one of them.
$1,000 for getting $1.00 on the wheel, introduced in 1975 = $4,765.09 in 2020
$100 perfect IUFB bonus, introduced in 1977 = $423.09 in 2020
$10,000 for winning Punch a Bunch, which debuted in 1978 = $39,324.23 in 2020
$10,000 for winning Grand Game, which debuted in 1980 = $31,115.78 in 2020
$5,000 top space in Plinko!, which debuted in 1983 = $12,871.18 in 2020
$500/card bailout option in Spelling Bee, which debuted in 1988 = $1,083.66 in 2020
$16,000 for winning It's in the Bag, which debuted in 1997 = $25,559.53 in 2020
