Magento 1.9 PayPal – Send Different Currency

One thing to do is to make sure that your call to paypal includes SOLUTIONTYPE=Sole as this should be the flag to inform paypal to allow guest checkouts.

1. If this flag is not set then you can investigate the Magento side to see why this is not being set of request,
2. If this is set but set to Mark then your config value is set to not allow guest checkout from the Magento admin config,
3. If this value is set then I would suggest there is a problem on the paypal side of things and would recommend getting in contact with them directly,

I hope this helps you find your issue.

First load currency loaded currency rates the multiple with product price

 $Product=Mage:getModel('catalog/product')->load($productId);
        $currencyModel = Mage::getModel('directory/currency');
        $currencies = $currencyModel->getConfigAllowCurrencies();
 $baseCurrencyCode = Mage::app()->getStore()->getBaseCurrencyCode();

        $defaultCurrencies = $currencyModel->getConfigBaseCurrencies();

                $rates=$currencyModel->getCurrencyRates($defaultCurrencies, $currencies);


                foreach($rates[$baseCurrencyCode] as $key=>$value  ) {
                    echo $key."-";
                    echo $price=$value*$Product->getPrice();
                    echo "<br/>";

                }
