I have a spreadsheet of all makers, their data, and sales for the past three years. If I count using this data then the answer is approximately 561,670.
However, there are a lot of holes which include: 1. the creators actually do not know how many they made or they do not want to publish the data. 2. Creators that did not set a mintage but just mint on demand. 3. What is actually qualified as a physical bitcoin (for example, do you count Coined Bits, Anonymous Mint, Silver Shields - they may mint unlimited amounts of these rounds forever)?
Good points.
I'd love a copy of that spreadsheet.
Various reasons a coin becomes a relic: They may be original, limited/mintage, a certain year, have historical significance, if they are out of business or not, Material, all sorts of things, the creators behind them.
I'm going to attempt to specify the differences
An example: "Physical Bitcoin Coin(s)" Represents Coins that have holograms and can, do or have held Bitcoin. Excluding all other cryptos.
Not all coins are treated the same. Some physicals bitcoins are not collectables yet. Most kind of are.
I haven't yet accounted everything but I know we are defiantly at 200k + with the count I have with these specified Paramotors. Again Its an attempt on good Guesstimate that is changing. It will continue to change in time and with more research into coins created.
Other Makers of Coins like "Bullion Physical Bitcoin", "Physical Litecoin Coins" or " Physical Monero Coins" that don't represent the paramotors of "Physical Bitcoin Coins" so should be classified a little differently and into its own category. This little classification really allows us to guesstimate the rarity of Particular or certain coins.
