There is a huge difference! Market value of an antique Bible is a function of many factors, and rarity is only one of those factors. Others include:
Let’s look at an example: A 1611 King James Bible First Edition is 393 years old and there are 200 copies known to exist. A 1560 Geneva Bible First Edition is 444 years old are there are 30 copies known to exist. Both are English language first editions of extremely historically important printings of the Bible. Which is older? The Geneva. Which is nearly ten times as rare? The Geneva. Yet, the market value of a 1560 Geneva (under $40,000) cannot compare to the market value of the 1611 King James (upwards of $400,000). Why? Because rarity and value are not the same thing… rarity is one component of value. In this example, there is simply more “market demand” for the 1611 King James.
Here’s another example: A four-leaf-clover is very rare. It is a genetic freak, occurring in only one out of every 2,200 clovers. The Irish have considered them “lucky” for centuries. What is the market value of this very rare item? Good luck selling it for $5! It has rarity, but little value.
So, even though that 1835 or even 1735 Bible you have may indeed be “rare” (there are not many of them), it’s still only worth less than $300, because it is not an historically significant printing, not a first edition of anything, not really that old, and has no market demand.
