To identify the authenticity of the gold leaf large gold circle, you can refer to the following steps:

2. Check the anti-counterfeiting pattern: The anti-counterfeiting pattern of the authentic product is three-dimensional and clear, while the fake product may be superimposed without a sense of three-dimensionality or layering.

3. Check the watermark: Genuine products have watermarks on the entire page, while fakes may not.

4. Check the printing process: the authentic fonts are full and the edges are clean, while the "gold leaf" words on the fakes may not be prominent.

5. Check the cigarettes and shredded tobacco: the cigarettes and cork paper of genuine cigarettes are yellowish in color.

The above steps can help you determine whether the gold leaf gold circle is genuine. If you have any doubts, it is recommended to ask a professional for identification.
