The Forge Domain cleric gets the Artisan's Blessing Channel Divinity option at 2nd level (XGtE, p. 19):
Starting at 2nd level, you can use your Channel Divinity to create simple items.
You conduct an hour-long ritual that crafts a nonmagical item that must include some metal: a simple or martial weapon, a suit of armor, ten pieces of ammunition, a set of tools, or another metal object. The creation is completed at the end of the hour, coalescing in an unoccupied space of your choice on a surface within 5 feet of you.
The thing you create can be something that is worth no more than 100 gp. As part of this ritual, you must lay out metal, which can include coins, with a value equal to the creation. The metal irretrievably coalesces and transforms into the creation at the ritual’s end, magically forming even nonmetal parts of the creation.
The ritual can create a duplicate of a nonmagical item that contains metal, such as a key, if you possess the original during the ritual.
When it says "you must lay out metal, which can include coins, with a value equal to the creation." It doesn't specify the number of items, even more, it just says "metal". Can I lay out several metallic items (metal sources) at once? I mean, for example, can I lay out 2 battleaxes (10 gp each one), 15 gold pieces and 10 silver pieces (27 items in total) to transmute an item worth of 36 gp?
