Yeah the all the released coins this month are over priced. The coloured typesets are dying a slow death, you cant sell any of the Snake releases for a profit (expect perhaps the 1oz proof).
So as it stands this is the situation. If you buy a coloured coin from the Perth Mint today you will immediately incur a loss (paper loss) of probably 10%-20% depending on the coin. Not really a good investment !
Buy shares today, do you immediately take a 10-20% hit? NO! If you buy silver bullion or gold bullion do you immediately take a 10-20% hit? NO!
So many better alternatives to investing for a profit than the Perth Mint's coloured metals program. In fact, I'd say the coloured metals program is a net loss maker - you are much more likely to cop a capital loss than profit buying into them.
