Turns out grandma's cookware is worth big bucks.

Social media is going bonkers for vintage Pyrex dishes -- the bright, colorful dishes decorated with floral accents.

Kathy Missal, who owns Recycling Retro in Woolwich and sells vintage Pyrex, says the sentimental value of the dishes is what makes them so special.

"Pretty much everyone that comes in to my shop relates to a piece that they see," she said. "They think of when they were growing up. Mom or grandmom, sometimes even great grandmom, cooked one of their favorite dishes."
