Out of the Collectors Auction House results, the Panda and Lunar coins you highlighted in your latest Pricepedia, and a few others, are below,
1983 S10Y Panda PF69UC SGD$4200 +12% Bid Fee/1.1235=USD3808, Pricepedia US$3670
1987 S10Y Rabbit PF69UC SGD $3400, USD3083, Pricepedia US$1867.
1998 S10Y Tiger Flower PF69UC, SGD$360, US$326, Pricepedia US$359
1996 S10Y Rat Piedfort PF69UC, SGD$1000, US$907, Pricepedia $1148
1987 G150Y Rabbit PF69UC SGD $2000, USD$1813, Pricepedia US$2164
1994 S10Y Dog Flower PF69UC, SGD$320, US$326, Pricepedia US$449 (last sale)
Big surprise on the 1987 Rabbit S10Y. Thats becoming the key. Piedfort silver still seems underbid compared to the 15g silver. Gold seemed slightly underbid compared to silver
Another surprise on the 1988 Cincinatti Expo Panda in PF69UC, SGD$2200, USD$1995. This coin prices at half that in Pricepedia.
The 5oz 1990 PF69UC Panda silver was strong at SGD$1100 (about 50% premium to Pricepedia).
The 1999 5oz Lunar silver Rabbit at SGD$1200 was a Black Friday door-crasher, selling for about a 2/3 discount to regular market.
The four Historical Figures sets (1990, 1992, 1993, all PF69 except one of the 1993 coins) sold for SGD$320/440/440. I expected prices around 50% higher. Maybe its the bigger holders and the hassle of converting holders causing some discount?
I also noticed quite a few of the gold coins (1995 & 1996 PF69 silk road, China 1979, 30th Anniversary of the PRC 400Yuan gold coins (lower grades) passed.
It seemed to me the most liquidity was reserved for 1oz silver pandas and lunars.
