Availability Index

The decision process to acquire a particular coin has been an interesting sidelight to this hobby. The rarity and quality issues of the "coin", the inital asking price, the depth of your pocket, the depth of the "other" bidders pocket stood out as early and primary factors in that process. Over the past two years I began to appreciate an additional factor, Availibility. How often will a coin appear in the market? Might the next one be a "better" deal? Will I be around to make that bid offer? I began collecting information about coins as they became available over the internet and to date there are over 1900 records distributed over 400 different obverse/reverse combinations. Availibility may become inconsequential if one aggressively collects, the information presented below should be veiwed as a passive measure of Availability. This information is offerred as food for thought. A - "not frequently available" to AAAAA - "come back next week and see what the next one looks like"
