How to change Currency Fields on the DetailView using the Sugar Bean

I am using SugarCRM 6.5.20 CE. I have access to the database and all files associated with this installation.

Problem: Add the '$' sign before fields that contain currency.

Solution: $this->bean->final_sale_amount_c = '$' . $this->bean->final_sale_amount_c;

This solution works on all fields that are text fields. It will change '75.00' to '$75.00'. But on fields that happen to be currency fields, the output on the DetailView is simply '0.00'.

I also noticed that the <span> class is equal to 'sugar_field' on everything but the currency fields which have no class.

I did

var_dump($this->bean->final_sale_amount_c);

And got back:

string(12) "75000.000000"

All fields except final_sale_amount_c, initial_deposit_c, and amount work fine.

Anyone know why this isn't working?

if(!defined('sugarEntry') || !sugarEntry) die('Not A Valid Entry Point');

function display(){

  var_dump
($this->bean->final_sale_amount_c);

  $this
->bean->initial_deposit_c = '$' . $this->bean->initial_deposit_c;
  $this

  $this
->bean->a_deposit_c = ($this->bean->a_deposit_c * 100) . '%';
  $this
->bean->b_deposit_c = ($this->bean->b_deposit_c * 100) . '%';
  $this
->bean->c_deposit_c = ($this->bean->c_deposit_c * 100) . '%';

  $this
->bean->a_quarterly_hosting_fees_c = '$' . $this->bean->a_quarterly_hosting_fees_c;
  $this
->bean->b_quarterly_hosting_fees_c = '$' . $this->bean->b_quarterly_hosting_fees_c;
  $this
