I recommend that you join both programs if you have not done so.
As an example, I’ve been giving this specimen some hard looks Proof gold 1 oz Princess Kaiulani
Current Price is $1,550
-Ebates 10% holiday special ($155.00)
-eBay bucks ($31.00)
If I win this auction the price will be $1364 (after refunds from both Ebates and eBay bucks).
Oh well, I have not moved on this coin since I already own the 1991 Princess Kaiulani proof gold set.
By the way, a Hawaii based dealer is offering a similiar coin for for roughtly $1000 more. Proof gold 1 oz Princess Kaiulani
Why the Princess Kaiulani interest?
I’m planning to ramp-up my writing on the Royal Hawaiian Mint issues of the Princess Kaiulani coins. This book is roughly 75% complete but was placed on hold due to the Presidential Medal of Appreciation series book release and related MoneyTalk presentation. I actually had a presentation scheduled at another coin show in late October, but had to cancel due to my father’s health. I’m looking forward in having this book released in 2016.
