The vendors for the big box stores often change the names, they may have given it the name 'Old Gold' but it really isn't related to the actually named one, most likely more their description for selling purposes. So you may never know which one it really is. I doubt it was
Rose (Rosa 'McGredy's Sunset'), too old and rare for something that a HD or Lowes would ever offer. My best suggestion is to try to find something similar that's more readily available.
