It seems like it, because the original Mahjong was a launch title for the Famicom, and for the Famicom Disk System. Somewhere along the line, a rare Hong Kong variant was released for that market which has different boxart than the japanese version and has a us version cartridge, which means it can be played on a NTSC console. Its pretty rare, so I could see someone charging a high price for that, but I don't think its really worth it, since its mahjong and its way cheaper to get the orginial Famicom and FDS versions, or just play it on a Japanese copy of Animal Crossing.
