Something else to consider would be the kind of money being used. In 1800 a buyer for a rifle would lay down hard gold coin. Say the piece cost 20 dollars and was extra fancy. Now add 213 years for inflation and a greater premium for the rarity of it's antique status coming through the years in good untouched condition. Take that amount and using actual antique gold coins from the period, you will get pretty close to what this rifle would go for today! :hmm:
