Magento: How to get actual price and special price of a product?

$_productId = 52;
$_product = Mage::getModel('catalog/product')->load($_productId);

Get Actual Price

// without currency sign
$_actualPrice = $_product->getPrice();

// with currency sign
$_formattedActualPrice = Mage::helper('core')->currency($_product->getPrice(), true, false);

Get Special Price

// without currency sign
$_specialPrice = $_product->getFinalPrice();

// with currency sign
$_formattedSpecialPrice = Mage::helper('core')->currency($_product->getFinalPrice(), true, false);

Note: static mixed currency (float $value, [bool $format = true], [bool $includeContainer = true])
