Should be approx. 28.4g. As it is likely that only one or two (if any) 1934 crowns found their way to China, then any defects to the original coin will be repeated on the reproduction. Essentially the process used is for the forger to employ the genuine coin as a hub from which he then cuts a die and ultimately copy coins from that die. For this reason, many of the copies are far from high grade and can be as low as fine. Unfortunately I do not know the particulars of any 1934 forgeries but someone else on here may know, failing that a search of the internet might yield an answer. Incidentally, there was a previous wave of forgeries emenating from the Middle East. I have now weighed the crown as advised and I am pleased to say it weighed 28.3g. Which hopefully is within the tolerance of the accepted weight of this crown and the weighing scales. With all your advice, I shall now consider my next move. Thank you for your help. Out of interest, which area of the country are you in? I'm in the East Of England
