Great response and I generally agree. However my research into the scarcity of the CDE prefix is also based on the lack of availability on major coin stores (Colonial, London Coin, Gatewest, JM, Monnaie Sherbrooke, etc...) all of which have the other prefixes but no CDE nor CDF's.
My other measure of Scarcity is that Im looking for one everywhere now and cant find it
..
When I first started pouring my paycheque into eBay, you could look at the online marketplace as somewhat indicative of what was out there. (IE: what sellers had & what collectors were buying mirrored the supply & demand situation) We all knew that it was probably 20-40% cheaper to buy online rather than walk into our LCS. [But you took your chances with the grading/condition of what you were buying].
Buying newer series (like original CDN Journey at the time) was mostly an eBay experience as most LCS only would sell Birds & earlier series. That was about 15-17 years ago when the
CPMF first emerged (& you could use the chatter here also as good indicator for who had what & who was looking for what). The
CPMF was a flurry of posts (activity) back then. And I felt we could buy notes for a fair market value since almost everything was
TAsL (
True
Auction
style
Listings) which started at $0.99. This was for mostly ungraded notes mind you (
TPG notes were just emerging with inconsistent results from PMG & PCGS).
Then eBay started tinkering around with their listing fees & started gouging sellers as the cost of the Final Value Fees sky-rocketed. Before eBay gouged everyone, 80-90% of the items listed were
TAsL & 10-20% were
BIN (
Buy
It
Now). Now a days, it has flipped-flopped so that 95% of the listings are
BIN & 5% are
TAsL. And it is practically impossible for a seller to use
TAsL & break even. For this reason, it is very difficult to get a handle on what is tough & what is not.
Feel free to contact me if you want an UNC CDE $10. You won't be able to find a better price I'm pretty sure.
