Found the solution. I'm posting my code below that worked for me. I had to go into my wp-content/plugins/woocommerce/assets/css/woocommerce.css to do it.
.woocommerce div.product span.price,.woocommerce div.product p.price,.woocommerce #content div.product span.price,.woocommerce #content div.product p.price,.woocommerce-page div.product span.price,.woocommerce-page div.product p.price,.woocommerce-page #content div.product span.price,.woocommerce-page #content div.product p.price{color:#85ad74;; padding-top: 10px; padding-bottom: 10px;}
Be sure to add some padding to it as it will overlap the title when you increase the font size.
@MoonDog, your suggestion made the prices bigger in the store listings grid. I needed to change that as well so thanks. But above is the code that made the price bigger in the individual product listing.
Thanks to all who have helped.
