Problem is they are making new ones every month and will only get better at it , the book could end up almost weekly .
IMO will only make new collectors pissed off as when they buy one and fnd its a copy will lose interest.
These in the years to come could of been the people buying forum members coins when they come to sell and can only damage the future of coin collecting.
There are people buying decimal coin copies for £50-£100 every day kew gardens ,lines on face etc.
Its not just the rare or scarce coins but the ones widely available that people dont look at twice that could cause a big problem.
