Poland Scott #64 (1919) Counterfeit?

[youpiao]

Can anybody tell if this one is coumtetfeit? The only thing I've found online says there are dots (similar to guidelines) in the margins that are the wrong diameter in the fakes. However, there are no dots on this example. Also, while the fakes are said to be more crudely printed, it is also said that there are crude looking real copies. Any other tells?

If it's a forgery, it's not the main type (large dots forgery).

To me, it looks good (non-expert opinion).
