Can't Lose On "100 For 100 Bison", But, Can You Make Money?

I would like to know what you have in your coin collection that met this criteria.

Market value for 20000/20000 penny roll is sure over $10000 now, compared with #19997 sale $3275.

So your coloration in roll value is that roll 20,000 is three more in number than 19997 and thus worth three three times. I think it is impossible to determine the value of a product based on auction results because the value from roll to roll will fluctuated based on bidders and the emotional investment of a bidder. It is possible for you roll to sell from $1 to $20,000 depending on the day and the people bidding.

By the way the same time you bought your roll I put the equivalent amount in BCE stock and have collected a couple dividends and sold for a 20% profit. I now have a profit of $1500, see that's something I can realize and measure, not your imaginary profit.

I estimate the valuse of 20000/20000 penny roll base on human common sense, not imagination. I believe most people have similar common sense like me, otherwise, who would bid #19997 to $3275.

If the fourth last penny roll (#19997) was bid to $3275, of course, I estimate minimum valuse of 20000/20000 penny roll is over $10000. Please do estimate from your deep heart, is it true that normal people will also estimate over $10000 on 20000/20000 penny roll?

See here is the problem. You are attributing your decision to common sense where common sense would involve logic and your decision to pay an exorbitant amount of money for that roll was based whole on your emotion and your own beliefs, not logic.

You accuse others of "estimate from your deep heart" where as that is exactly what you are doing. The is no logical basis for your estimated roll value. Different rolls will not trade on the same proportionate scale. Also you can not prove anything statistically with a sample of two. You must use more samples. The price of roll 19,997 could have been an anomaly. In order to truly determine the value of your roll you will need to analyze the price of significantly numbers rolls over a longer period of time to determine a price curve. My point is that there is no way to price your roll at this time without sending it at auction. My advice to you is if you get an outrageous offer for that roll, sell it now, don't even think about it. Profit realized is much better than potential profit.

Also if you sell it in an auction house prepare to pay 20% to 30% commission to the auction house.

I'll let you know in six months :)

I got #2000/20000. How much the market value do you thinking?

Imagine you spend $1000 on 20 for 20 / 100 for 100 series, you'd rather have 10 pcs different 100 for 100 coins, or 50 pcs different 20 for 20 coins? Which way do you think your collection is much cooler?
