array uitlezen met key and value

Ik probeer mijn array uit te lezen met één foreach

<?php
$specialprice = array(
	'2' => '1,75',
	'3' => '1,62',
	'4' => '1,61',
	'8' => '1,59',
		
	);


foreach($specialprice as $price => $value){
	echo $price -> $value;
}
?>

Nu krijg ik deze error
NOTICE Trying to get property '1,75' of non-object on line number 12
NOTICE Trying to get property '1,62' of non-object on line number 12
NOTICE Trying to get property '1,61' of non-object on line number 12
NOTICE Trying to get property '1,59' of non-object on line number 12
