Append to Currency Field in Sub Panel

Hello all,

I have a sub panel that has a currency field being displayed as $2.74. I would like to be displayed as $2.74 lb. Is this possible? I have altered other field types without any issues using a process_record logic hook, but the currency field is not doing this. This is what I am trying:

$bean->cq_yarn_color_cost_pound = $bean->cq_yarn_color_cost_pound. ' lb';

I have also tried:

$bean->cq_yarn_color_cost_pound .= ' lb';

This results in both cases is $2.74.

Thanks for any help you can provide.
